Transdisciplinary Math – An epiphany and a plan!

For the past few weeks I have been helping my teams review their math scope and sequence and decide which math is transdisciplinary and fits within a Unit of Inquiry and what math is better taught in stand-alone units. This process always seems to lead to the same conclusion….

Teaching math in a transdisciplinary way is hard. 

Teachers seem to believe in the purpose and power of teaching math in a relevant and significant context and want to do it… but most seem not too sure about how to do it.

As I get ready to transition back into the classroom in the fall, this is something that has started to occupy my mind as well. How DO you do it? The last time I was a PYP teacher I can self-admit that teaching math within the context of my UOIs was not a strength of mine – in fact, I’m not sure if I did it at all. So naturally, this is an area I want to get much better at. But how? 

And then I had an idea! It hit me this weekend while I was watching BBC’s Africa series.

Since teaching math in a transdisciplinary way was on my mind, I couldn’t help but notice that every vignette was OVERFLOWING with opportunities for math inquiries!

The average size of a giraffe’s tongue is half a meter.”

“Only one out of 1000 turtles make it to adult hood.”

One million birds migrate over the Sahara each year.”

“Each chick weighs only 20 grams.”

“The adult grows to be 5 times the size of the baby.”

“Silver ants can only survive in the sun for 1 hour.”

Every few minutes there was some piece of information about an animal or a landscape or a natural phenomenon where you needed to understand the math concept being referenced in order to fully understand what was being said. And that is when it hit me! All of the movies, books, articles, graphics etc. we use in our Units of Inquiry probably already contain opportunities for math – we just need to be looking for them and know what to do with them!

So here is my plan for next year!

Step 1- Introduce a text related to the central idea or the central concepts.

As usual, choose (or invite your students to help choose) a resources to explore the big idea in your current Unit of Inquiry. Introduce the text in an open-ended way. Allow the students to engage with the text in a natural and organic way. Read the book. Watch the movie. Listen to the song. Look at the info graphic. Allow the students to enjoy it and ask questions, make connections and offer thoughts. I’m thinking of using a back channel like Today’s Meet to allow students to communicate their thoughts, reactions and questions with their learning community while watching, listening or looking without interrupting one another. You could also provide post-its so students could record their thinking if a device is not available.

Step 2 – Revisit the text with a math focus

The next day, revisit the same text, but this time let students know that they will be looking at the text as mathematicians. Re-read the book. Re-watch the movie. Re-listen to the song. Re-look at the infographic. But this time, stop and pay specific attention to the “math moments”. If the video says “Giraffes’ tongues are half a meter long” pause the video and ask students, “What does that mean?” “How long is that?” “How can we find out?” “How can we show it?”. Any time a number, a measurement, a statistic, a pattern, or a concept is mentioned stop, point it out and explore it.

Step 3 – Follow where it takes you

When you stop to explore the math within a UOI text, be prepared to follow the inquiry. If it takes 10 minutes great. If it reveals other math concepts, skills and vocabulary that need to be explored first, back up and inquire into those. If your students need to bust out some manipulatives, look online, consult other mathematicians – do it! Allow what ever time is needed to explore and truly understand what the math means in that context.

Step 4 – Don’t stop at math! 

After the initial open-ended viewing and the math-specific viewing… keep going! You could apply the same strategy for many different purposes. Explore the same text a third time with a writer’s lens and hone in on the techniques the writer used. Explore the same text with a musician’s perspective and focus on how different segments of music contribute to the message. Explore the same text from an artist’s point of view to analyze colour, line and shape that was used. This would be a great opportunity to connect with single-subject teachers and share some of the texts with them to be looked at and deconstructed multiple times, in multiple ways, through multiple disciplinary-perspectives. Your whole week could be deconstructing one text in different ways for different purposes!

Eventually, I believe you will be able to get to the stage where instead of telling students “here is the math” when exploring a UOI text, you will be able to ask them “where is the math?”.  I also have the sneaking suspicion that if you allow students to document their thinking during the initial, unstructured exploration of the text there will be some math-related questions that are recorded about the quantities, measurements and statistics that are referenced. So you wouldn’t even need to point out the math, you could allow students’ own questions to be the driving force of the math inquiry.

So I challenge you… go back and look at some of your UOI books, videos, graphics etc and notice the opportunities for “math moments” and more!

How do you explore your UOIs through the discipline of math?

What are your best approaches to inquiring into math within the context of a UOI?

Inquiry Based Math Strategies

During our half day of Personalized Professional Learning, I hosted a workshop on inquiry-based math strategies, but not everyone who wanted to attend could attend… so I thought I’d recap the workshop here for those of you who could not make it – and for those of you at different schools who might be interested in this topic as well.

The structure of the workshop was very hands on, so in the absence of you being able to actually engage with the materials and manipulatives, I will provide a combination of notes, photos, questions and reflections that will hopefully allow you to engage in some of the same ideas, just in a different way.

Tuning in – What do already know?

Think about or jot down your current understanding of each of the inquiry-based math strategies listed below:

  • math time capsule
  • open ended centers
  • magic question
  • open-ended questions
  • number talks
  • math congress
  • visible thinking routines
  • inquiry cycle

If you have a thorough understanding of each of these strategies, you probably do not need to read on. If you think your current understanding has room to grow, read on!

Open-Ended Centers

I’ve already written a post about open-ended math centers and how they work in our early years classrooms. During the workshop today, each group had a bin with the three essential ingredients of an open-ended math center: manipulatives, writing utensils, and a placemat/whiteboard.

Here are some pictures of how teachers tested out a few open-ended math centers:

math workshop 3 math workshop 2 math workshop 1

The Magic Question

I’ve also written about my favourite inquiry questionWhat do you notice? In the workshop we looked at how this question can be used for math specifically.

Take a look at this multiplication chart. What do YOU notice?

Open-Ended Questions

Answer this question: Compare the following fractions using < > or =

1/4   ____  1/2

Now answer this question:

What is the same as a half?

Reflect on the difference between answering the first and second question. What are the benefits of asking open-questions in math?

Number Talk

Take a look at the following image. How many dots are there?

How did YOU figure it out? Here is a picture of all the different ways the participants of the workshop figured it out.

math workshop 8

Math Congress

Step 1 – Present the problem: A sports store has a number of bicycles and tricycles. There are 60 wheels in total. How many of each kind of bike could there be?

Step 2 – Work towards solving the problem. Markers and chart paper work best!

math workshop 6 math workshop 5 math workshop 4

Step 3 – Share discoveries and strategies with fellow mathematicians. Make sure fellow mathematicians are invited to ask questions, make connections, comments and conjectures!

Visible Thinking Routines:

Use the Visible Thinking Routine “Claim, Support, Question” to share some of your thinking about decimals.

CSQ

There are also many other Visible Thinking Routines that are helpful in approaching math in an inquiry based way!

Inquiry Cycle:

Kath Murdoch’s inquiry cycle is a great way to make any math more inquiry-based.

A CCSS math standard: Know and apply the properties of integer exponents to generate equivalent numerical expressions.

What do YOU already know about this?

What do YOU need to find out about this?

How could YOU find out about this?

Math Time Capsule:

Now, think about or jot down your understanding of each of the inquiry-based math strategies listed below. A math time capsule is a great way to show growth and progress in math – whether it’s over the course of a unit, a year… or even of the course of a workshop!

  • math time capsule
  • open ended centers
  • magic question
  • open-ended questions
  • number talks
  • math congress
  • visible thinking routines
  • inquiry cycle

How did your understanding of these strategies grow and change?

In the actual workshop, after each strategy, we took some time to discuss how the strategy could be applied/adapted to different content and different age levels. Too often when we are looking at strategies we are focused on the actual strategy within to confines of the example that is used. This leads to the conclusion that “That doesn’t work for the grade/content that I teach”. Instead, I challenged the participants in the workshop – and I challenge you in the same way – to focus on the essence of each strategy and how that same approach can be used in different ways, for different ages and for different strands of math.

Here are a few examples of how the same strategy can be adapted for different content and different ages:

Math time capsules – In Grade 5 you might give students the summative task on the first day and then again on the last day to show all of the growth and progress they experienced. But in KG, you may conference with a student and voice/video record everything they know about shapes, and then record them again at the end of a unit to capture growth in their understanding.

Magic question –  In KG you might show a ten frame and ask “What do you notice?”. In Grade 2 you might show a hundreds chart and ask “What do you notice?”. In Grade 4 you might show a multiplication chart and ask “What do you notice?”.

Inquiry cycle – In Grade 1 you may use the inquiry cycle to structure a whole class inquiry into measurement. What do we know about measuring objects? What do we want to know about measuring objects? How can we find out more about measuring objects? In Grade 6 you might use the inquiry cycle to structure self-directed, personal inquiries towards calculating volume of 3-d shapes. What do I already know about finding volume of 3-D shapes? What do I still need to find out? How can go about that?

The possibilities are endless. If you focus on the “why” a strategy is effective and “how” a strategy helps foster thinking and exploration… then the “whats” become infinite! I also shared this google doc with some of my favourite inquiry-based math resources (books, blogs and Tweeters!) Feel free to have a look!

How Children Learn Math: Bringing it Altogether

Last year I wrote a post about what the PYP believes about how children learn math:

  1. Students construct their own meaning about math
  2. Students transfer their meaning into conventional symbols (vocabulary, notations, algorithms)
  3. Students apply their understanding to problems and real world contexts

I also shared some examples of how teachers at our school have been helping students to construct their own meaning about mathematical ideas and concepts. A lot of the teachers I work with are feeling confident about that first stage in the math cycle! However, they are still wondering how to bring all 3 of the stages together.

In an attempt to step back and see the big picture of how the stages fit together, our teaching teams generated a list of all the math strategies they use in their math programme.

Presentation1

Once the list was compiled, they asked these three questions:

What strategies give students the opportunity to construct their own meaning?

What strategies help students to transfer meaning into symbols?

What strategies provide students the chance to apply their understanding?

Then, they sorted each strategy into each phase of the math cycle. (Along with some amazing debates, disagreements, discoveries and many references to the PYP Math Scope and Sequence document!) We discovered that many strategies fit multiple stages in the math cycle depending on the question you ask or how you present it. We also spent a good chunk of time discussing how many of the strategies that allow students to construct their own meaning at the beginning of a new unit or new concept, would also be good at the end of the unit to allow students to apply their understanding using conventional symbolic representations.

It is interesting to note that no two teaching team’s chart looked the same. Another point for acknowledging that all learners construct their own meaning in their own way!

Here is the chart our Grade 3 team developed:

Math Strategy Sort

Now when we are planning a stand-alone math unit, we have an anchor chart that will help us purposefully select math strategies to support students as they to move through all three stages of the math cycle.

How do you bring the three stages of how children learn math together?

Open-Ended Math Centers

At our school, we strongly believe in the benefits of inquiry, exploration and play based learning – for all of our students, but especially our youngest students in KG (kindergarten). One of the best strategies our teachers implement are open-ended math centers.

Here are a few reasons why we love open-ended math centers:

  • open-ended math centers have no start or finish, which means there are never students who are ‘done early’ and never students who need to ‘finish their work’
  • open-ended math centers allow students of different abilities to self-differentiate and explore the math concepts and skills they are developmentally ready for
  • open-ended math centers allow students to construct their own meaning, collaborate with their peers and engage in authentic conversations about math
  • open-ended math centers allow teachers to observe and collect assessment data in a non-threatening, non-stressful environment.

Take a look at some of our open-ended math centers in action. What do you notice?

Here is a sneak peak into how we plan for open-ended math centers:

building blocks

number cards

playdo How do the numbers look different? How do they look different?
Choose two numbers. One of them is a lot more than the other. What are they and how could you write them?

We are always growing in our own understanding of math centers and play-based learning, so we would love your feedback about our open-ended math centres. We would also love to hear about and see what early math learning looks like in your classroom! 

Learning Time Capsules – shifting the focus from achievement to progress

Here is an example of how one of our Grade 4 teachers is shifting his students’ focus from achievement to progress through the use of a math “time capsule”.

Diagnostic: This teacher looked at all the big concepts the Common Core outlined for fractions in Grade 4 and created open-ended questions to allow students to show what they already knew or thought they knew about each big idea. Students were encouraged to be risk-takers and try every question!

Grade 4 Open Fractions

The teacher then tracked students’ prior knowledge on an excel sheet. This allowed him to plan full group, small group, guided and individual math inquiries based on needs.

Formative: After a few weeks of inquiring into these fraction concepts, the teacher gave back the same task and highlighted questions that students were required to try (based on the concepts that had been learned over the past few weeks in class). Green meant they showed competent understanding the first time they tried the question (during the diagnostic), but could still show extended understanding if they added to it. Pink meant they had not previously attempted it or showed a developing understanding and would need to add or change their answer. Students were encouraged again to be risk-takers and try the questions that were not highlighted, as their new knowledge and understanding might help them figure out concepts that had not yet been explored as a class.

Grade 4 Fraction formative

The teacher then added this formative data to the excel sheet to show the progress each student had made in each area, who was ready for a challenge and who needed more support.

Students were also given the chance to reflect their own understanding of the concepts learned in class so far and indicate which areas they were feeling confident in and which they wish to work on more. The teacher also filled in the same feedback sheet which highlighted his perspective on what the student did well and what they could still practice. This feedback was shared with parents along with recommendations for support at home.

Stars and Wishes Template

Summative: At the end of the Unit, the teacher gave the same task back and the students were instructed try every question in order to show their final knowledge and understanding. Again the questions were colour coded so students knew which of their answers showed a competent understanding and which answers needed to be added to, changed or attempted. Prior to handing out the time capsule, the class came up with a student generated rubric for each question, indicating what would show a competent or extended answer. Students had access to both an electronic and paper copy of the rubric to help them understand how to be successful at each question

After completing the time capsule, students completed the Visible Thinking Routine “I used to think… Now I think” to reflect on how their thinking about fractions changed from the beginning of the unit to the end of the unit. The time capsule, self-assessment rubric and meta-cognitive reflection were all sent home so students could share their progress with their parents.

Used to think now i think

When the focus is on achievement, students have no choice but to compare their achievement to the achievement of others. But when you place the importance on progress, students focus on how their knowledge and understanding grows and changes over time. Each time the students added to or changed their time capsule it was a visual representation of how their knowledge and understanding had grown and changed. Each student felt successful in his or her own way because they could see the progress they made over the course of the unit.

How do you help your students focus on progress and growth?

We tuned in!

Before our Units of Inquiry started, grade-level teams inquired into “tuning in” (with the help of  this post from Kath Murdoch). Many teachers walked away with a new, or deeper, understanding of the purpose behind the “tuning in” phase of inquiry. Teachers were excited to put their new learning into practice… here is how it turned out in our Grade 1 to 5 classes:

Grade 1: Peaceful relationships are created through mutual understanding and respect.

Students tuned in to problems and solutions:

Students tuned in to the concept of numbers:

Grade 2: Citizens build communities.

Students tuned in to the concepts of “community” and “citizenship”:

Grade 3: Decisions impact conseqeunces.

Students tuned in to “decisions” and “consequences”:

Grade 5: Relationships among human body systems contribute to health and survival. 

Students (and teachers) tuned in to the concept of systems:

I love that the students’ thinking is front and centre!

I love that the students’ thinking is visible!

I love that students were able to demonstrate their thinking in a variety of ways!

I love that teachers tuned into conceptual understandings, not just topic knowledge! 

I love that transdisciplinarity is evident!

I love that teachers were acting as inquiries themselves… doing reconnaissance to find out about what their students bring to a Unit of Inquiry!

The feedback from teachers about “tuning in” has been great! Teachers are excited because they have learned about their students’ prior knowledge, their misconceptions, their interests and their questions. It has not only provided them with diagnostic assessment data, but also a road map that illuminates “where to next?” based on students’ needs and interests! I can’t wait to see where these inquires lead!

How do you “tune in” to your students’ thinking?

Classroom Set-Up: How much should we be doing without students?

Every year many teachers spend hours upon hours setting up their classroom to ensure it is picture perfect before the students arrive.

classroom on the first day
But I wonder, by doing so, are we taking away some great learning opportunities for students? In PYP classrooms, we start the year with blank walls to ensure there is lots of space to display students’ questions and students’ thinking, but what other classroom set-up jobs should we be sharing with students? Involving students in classroom set-up is not only a great way to build a sense of community and send the message that it is our classroom, not my classroom,  but their are also some great opportunities for math, literacy and transdisciplinary skills… if you’re looking for them!

Here is a list of some typical classroom set-up jobs that involve literacy, math and transdisciplinary skills that could be shared with students:

Covering bulletin boards: measurement, surface area, cooperation, problem solving, group decision making, planning skills

How much paper will we need to cover this bulletin board? How can we figure it out? What tools could we use? Is there another way to figure that out? 

bulletin board cover

 

Bulletin board borders: measurement, perimeter, repeating patterns, adding, multiplying, creativity, planning, organization, fine motor skills

How much border will we need to go around the outside of the bulletin board? How can we figure that out? How wide should the border be? How do we know if we have enough? What designs can we put on the border so it is appealing to the eye? 

border

 

Sectioning Bulletin Boards: Shape and space, measurement, division, fractions, arrays, problem solving, cooperation, analysis, spatial awareness

How many equal sections do we need? How big will they be? How many rows and columns can there be? How can we be precise? How can we section them off?

sectioned bulletin board

 

Arranging desks/tables: equal groups, shape and space, multiplication, division, problem solving, listening, speaking, planning, gross motor skills, safety

How many different ways can we arrange our desks into groups? How many different ways can we arrange our desks into equal groups? How can we set up our tables to maximize the number of chairs that fit around? Which arrangement gives us the most space? 

desk set up

 

Name tags: Literacy, printing, letter formation, capitalization, non-verbal communication, respecting others, planning, organization

How we can show which cubby belongs to who? Why do we need to label cubbies? What do we need to remember when we write our names? How can we make sure our letter are the proper size and shape?


cubby label

 

Classroom Library: sorting, genre, organization skills, labelling, counting, adding, estimation, planning, group decision making

How can we organize our books? Is there a different way to organize them? Where should we put them? How should we label them? What are the fancy literacy names for these kinds of books? Where can we find out? How many do we have in total? How will people know where to put them back?

class library

 

Toy Shelves: sorting, labelling, organization, systems, cooperation, making group decisions, planning, speaking, listening,

How can we sort our toys? How can we keep them organized? What should we label each bin? How will students know where to put them back?

toy shelf

 

Student-Made Class Alphabet Strip: Literacy, letter formation, letter sequencing, letter sounds, upper case and lower case, writing, synthesis, fine motor skills, team work

How do we make this letter? What word starts with this letter sound? Which letter comes next?

alphabet strip

 

Student-Made Class Number Line: Counting, sequencing, quantity, number formation,writing, synthesis, fine motor skills, team work

How do we make this number? How much is that number worth? What number comes next? What is the name of this number? How do we spell it? How do we make/spell this number in our other language?

nunmber line

 

 

Class Schedule: Measurement, writing time, lapsed time, adding/subtracting/dividing time, fraction, percent, analysis, evaluation, planning, time management

How can we split our classroom time? How can we make a schedule that has x minutes total for literacy/math each week? How long is in between first recess and second recess? How can we show that this class is 45 minutes long? How can we display our schedule?

 

schedule

 

As with most things in PYP/inquiry-based teaching it can seem that the teacher’s role is minimal. Quite contrary! In order for a teacher to share the classroom set-up duties with students, there is much thinking, planning, organizing and orchestrating needed on the teacher’s part in order for this to be successful and meaningful to students. Here are a few guiding questions to help with this:

1. Which tasks are appropriate to share with the age of students I teach?

2. Is there purposeful literacy, math or transdisciplinary skills in this task for my students?

3. How can I organize this process? (What materials should I have ready?  How long will it take? How should I split the students in to groups?)

4. What questions can I ask to guide the process and maximize student thinking?

5. Is the juice worth the squeeze? (Do the benefits of having students involved in this task justify the time it will take?) 

To be perfectly honest, I have never tried this myself… but I wish I could have before I left the classroom! I think there are so many authentic literacy and math skills needed to set up a classroom that require social, communication, thinking and research and management skills – both by the students doing them and the teachers planning them!

Have you ever tried this before with your class?

Do you have any advice for teachers trying this for the first time?

What other classroom set-up jobs would you add to the list?
