On April 16, 2025 I had the pleasure of presenting my workshop Bringing Math to Life: Sparking Joy and Curiosity through Play for Early Childhood Investigation Webinars! With over 3000 registrants it was my largest audience to date! I absolutely love inviting educators into my kindergarten classroom and sharing the rich math learning that children experience through play and inquiry! Connecting with others drives my practice and inspires me greatly! A big thank you to all who attended! A copy of the presentation slides are available and can be found at this link.
I am a Reggio Emilia inspired Full Day Kindergarten teacher and mother to three young children. This blog is meant as a communication tool for the families of our children and as a learning tool for the many educators who follow us. Please feel free to comment on posts and participate in our collective understanding of emergent curriculum.

Calendar Math: Daily Date-Inspired Prompts to Inspire Math Talk

Math talks are regular, short conversations about purposeful math problems with children. These are intentionally crafted to invite children into specific math situations, helping them to improve their mathematical confidence and abilities. Math talks are meant to be open-ended opportunities that have multiple entry points and approaches for interpreting and solving the problem. To learn more please read my article Joyful Number Talks in Kindergarten available here:
The Journal of Teaching and Learning
Vol. 13, No. 2 (2019) pp.43–54
https://jtl.uwindsor.ca/index.php/jtl/article/view/5684/5082
In my classroom I engage children in daily math talks during our first whole group time together. I often use the date as a focus for the number talk. For example, if the date is December 10, I use the number ten as the focal point of our math exploration.
Over the years I have shared my math talks on social media and have been asked repeatedly to create a guide to support educators who wish to engage their students in math talks. This served as the inspiration my book Calendar Math. This book provides photo prompts and accompanying questions is that educators can use these to engage children in regular conversations in the classroom. In the book each calendar date (numbers 1 through 31) has four different pages with accompanying prompts. Use them for different months and also as sparks for creating your own daily number talks with children.
To help educators get started here is a collection of photos representing the numbers 1 to 31 available as a PDF file. They can be digitally projected or printed and used as part of your morning math talk. Feel free to use them to support and supplement math discussions with your students!

See, Think, and Wonder Math Routine Using Videos
Math is all around us! As an educator I love helping children discover the authentic ways we use math in our everyday lives! As children recognize the integrated, meaningful ways math helps our world work, their interest and confidence in the subject will grow. Exploring the authentic math that exists in our surroundings may help nurture children’s interest and confidence, building a strong foundation for subsequent experiences.
The ‘see, think, and wonder’ routine is a specific sequence of steps that guides children’s thinking regarding a specific observation. Children first describe what they see, focusing on their power of observation. Next, they interpret these observations and articulate connections to what they have seen. Finally, they share a question or wondering about the object in order to guide their future thinking work.
The 'Winter Day - See, Think and Wonder' video can be used in physical or virtual learning spaces to help facilitate math conversations. At first children can be invited to carefully observe each photo and share what they see. Ask children to use rich description as they articulate their observations. Next, ask children to make personal connections to the information presented in the text and photos. They can articulate what they think about the question prompts in the text, or make inferences about the information shared in the photos. Finally, ask children to share what they wonder about the text and photos. Educators can pause the video at any point to give children more time to engage in math conversation about their observations and wonderings.
As children engage in conversation, reflect upon their ideas. What are children curious about? What do they notice in the foreground, and background of each photo? What connections can they make to the video? What experiences do they have that relate to the objects or situations being presented? Is there something they are interested in learning further? How might they go about conducting mathematical research if they have access to these objects or scenarios in real life? What knowledge do they need to have in order to research their question? What tools and supports might help them in their quest? How can they share their findings with others?
After the children have explored the video, consider asking them to co-create their own version of the media in the form of a 'See, Think, and Wonder' class book. Children can illustrate pictures and write their own narratives. Invite children to look around their homes and communities for other seasonal situations to explore. Perhaps children can digitally document what they find and add these to their own Winter Day book. Images can also be gathered and shared in a video form. The possibilities are as endless as the questions children ask.

Cultivating a Classroom Space for Math Learning
“Do not wait until the conditions are perfect to begin.
Beginning makes the conditions perfect.”
Alan Cohen
As we head back into the school year many educators are working
thoughtfully to create environments that are rich with math possibility.
In Reggio Emilia the environment exists as the 'third teacher'
inspiring, supporting, and extending children's learning in rich and
complex ways. I have been contacted by many educators asking for advice
on how to best set up their classroom and routines in order to create as
many opportunities for authentic math as possible. This has inspired
today's blog post - how to cultivate a math rich learning space for
children at the beginning of another school year. (I recognize that many areas will have Covid restrictions and following the advice of your local health unit will be important as you plan for your programming.)
When I reflect upon my own math pedagogy
and practice these are what I think stand out as mathematically
meaningful for the educators, children and families that share our
space. Although this check list isn't all inclusive, I thought it might
spark some ideas to support and inspire as we enjoy the final weeks of
summer and start back in our classroom with open eyes, minds and hearts
this year.
1. Make math a part of every space in the classroom and child's school world. In
the classroom are there math tools and materials available for use
beyond a 'math center or math shelf'? Do children see how math relates
to every subject in the space (e.g., how materials are sorted and stored
on the toy shelf, how measurement is used when children decide on a
size of paper to use for their project)? Can they translate math tools
and ideas into other spaces in their immediate school world (e.g., see
how math relates to their walks in the hallway or work in the gym)?
2. Ground and build math concepts into known objects for children.
When introducing, extending or innovating a math idea is it organic and
natural to the child's explorations and world? For example, it is more
natural to engage children in an exploration of measurement if they
measure things in their immediate world using the stick they are playing
with, instead of using a standardized ruler (e.g., "Can you find
something the same length as your stick in the yard?", "What is taller
than your body?").
3. Use available math moments with children. In our classroom we
have a large block of uninterrupted play each day. It's sometimes
challenging to manage children, materials and activities during center
time. However I try to engage with children as much as possible in the
activities, and take on the role of 'play partner' together with them.
When I am actively playing I am able to closely observe what they are
saying and doing, helping me to identify and extend the rich math
learning that is organically occurring (e.g., helping children to
recognize why their tower keeps falling, using math terms when they
equally share the play dough, introducing math terms as they discuss how
many cars are in their parking lot).
4. Become a math role-model for children, families, and colleagues. Even
if math isn't your favourite subject, how do you discuss it within your
school and classroom? Are you excited by new activities and resources?
Do you demonstrate a growth mindset? When mathematical situations
arise with children that you aren't sure of, can you use these
opportunities to showcase positive thinking and problem-solving? Share
your new math learning with others - suggest articles and books you're
reading and post these throughout your classroom to enhance
documentation displays.
5. Find the math in everything. Many educators plan forward by
choosing curriculum and programming expectations and then building
activities to fulfill these. Try back-mapping activities from time to
time; embrace child-centered, organic experiences and then deconstruct
them in order to identify the rich math concepts and curriculum
expectations that they utilize. You'll be surprised to find that math
happens in almost every experience children have in the classroom.
6. Try looking at life through a mathematical lens. When planning
invitations for learning in your classroom, see what math you can sneak
in as well. Changing one or two elements of the experience might be
enough to engage children in rich math. It reminds me of how I used to
sneak veggies into my children's meals - a little can go a long way!
7. Collaborate mathematically with colleagues. Share new ideas
and resources informally. It's easy and effective to create math
invitations and activities and share these within your school or
division. If every educator plans one or two activities and these are
shared, children will benefit from many rich and interesting games and
activities without the burden of planning and preparation it would take
one educator to accomplish the same.
8. Record and celebrate your math moments. Help children,
families, and colleagues recognize that math happens everywhere in the
classroom by creating a documentation display with photos, anecdotal
observations and connections to curriculum. This bulletin board can be
built over the course of the school year as artifacts of learning are
continually added by staff and students. Keep sticky notes nearby and
invite observers to record their own ideas and share them by posting the
notes within the documentation.
9. Engage families in joyful math with children outside of school. Consider
ways that you can promote and extend math for children after school.
Encouraging families to play math games and activities together with
their children will not only provide children with additional meaningful
math moments, but it may help older family members reconcile their fear
or dislike of math. In our classroom we send home family math bags
once a week. These are filled with math invitations and materials so
that children and their families can play games inspired by our
classroom work.
10. Build your collection of math stories, songs and games. Children
love to sing, dance and play games. Ask colleagues to share their
favourite games and activities, and use these to help with transitions
and other 'math moments' throughout the day. Quite often the words in
songs can easily be improvised to match something happening in your
classroom, and many rich storybooks have mathematical elements and
problems embedded within them that can inspire children.

Which One Doesn't Belong? Using Autumn Treasures to Inspire Math Talk
The children were gathered for whole group. I displayed a collection of pumpkins and asked them a question - which one does not belong?

- develop specific content ideas
- meet different standards
- develop playful mindsets in children
- practice problem-solving models
- facilitate communication skills

- what is the purpose of the math talk?
- what big mathematical ideas are you hoping to embed within the conversation?
- what are the needs of children and is the talk differentiated enough to include all?
- what directions do you anticipate the conversation taking?
- what assessment opportunities will the math talk provide?
A starting point for any math conversation is to provide a tangible artifact for children to explore (e.g., a pumpkin, piece of artwork, collection of loose parts) and ask them to notice and name what they see. Once they articulate their observations about characteristics of the object (e.g., shape, size, colour, texture, smell) they can make connections between these and the world around them (e.g., other objects, experiences, texts). Perhaps questions emerge in the conversation and children can wonder about some element of the object or conversation. This can lead to a research query to explore further.

Exploring the Outdoors Mathematically with the Five Senses
*What patterns can you see and identify in our space?
*What shapes do you notice in your surroundings?
*Can you locate different numbers or groupings of objects? A pair? A group of three, four, five, etc. *How many different shades of one color do you see?
*Can you group objects based on a sorting rule?
*What’s a reasonable estimate for something large - how many leaves are on the tree? How many ants might be in the garden?
*Can you search the yard and locate/match similar objects based on how they look?
*Play a game of “I Spy” using math language and encourage children to make predictions on what object you are referring to (“I spy with my little eye something larger than my hand…. Something taller than our fence…)
*Can you describe the object in a mystery bag by how it feels? Can you guess what it is?
*Run your hand along a patterned object and describe what it feels like.
*Can you sort objects based on how they feel (hard, soft, squishy)?
*Encourage children to create a collage using natural objects they find in the yard. Identifying the object’s characteristics and then classifying and sorting helps children build data management skills. Children can discuss the inspiration behind their choices or their placement on the collage.
*Bring sculpting materials outside including play dough or clay and encourage children to sculpt it using natural loose parts. What prints can they make in the dough using different objects including pinecones, leaves or sticks? Can they see or feel patterns pressed in the dough? How do they describe these patterns to others? Can they continue a pattern?
*Give children touch challenges - who can find the heaviest item in the yard? How many children does it take to lift this object? Is it even possible to lift it? How do children problem solve when they find an object that cannot be moved? Can they find the lightest? Can children order a collection of rocks by weight (lightest to heaviest) or flowers by shades of the same color (lightest to darkest)?
*Ask children to feel different objects and describe their temperature. Are items hot? Cold? Can their properties change if heat or cold are added?
*Harvest seeds, fruit or veggies from a garden and ask the children to count how many of each item they have grown. Can children measure to see how long their fruit or veggies are? Provide samples of each food and have children vote on whether or not they enjoyed the taste. Children can write their own recipes using these harvested foods and experiment with preparing or cooking them in different ways.
*Offer children foods grown from the local area. After tasting samples of each ask the children to classify the foods using a common characteristic (crunchy, sweet, tangy, mushy, sour). Photos can represent each food and be placed in the appropriate place on a sorting ring or on a chart.
*Encourage children to go on a ‘smell hunt’ around the yard and find natural items with different kinds of smells (sweet, strong, unpleasant). Children can place the object on a chart placed in a central location. After the hunt children can calculate how many of each item were found.
*Play a game of mystery smell. Place an object in a bag and have children close their eyes and smell. They can use language to describe the smell and then indicate whether or not they liked it by voting on a class chart.
*Children love to create their own ‘potions’ outside. Often when objects are crushed they release a stronger smell. Encourage children to create their own recipes or smell equations by gathering different objects outside and mixing them together. Children can also use large rocks to crush and mix the objects together. Provide clipboards and pencils so children can write down their ‘equations’ (10 rose petals plus a handful of grass equals a sweet and strong smell).
*Ask children to use their bodies to make different sound patterns. They can clap, stomp their feet, tap their knees, and snap their fingers in different rhythms. Play follow the leader where one child plays a pattern and the others have to repeat it. Children can articulate the pattern rules they hear (one clap, two stomps, one clap, two stomps).
*Study different animal calls - many have a repeating pattern in their sound. Play recorded animal calls on the iPad and ask children to describe what they hear. Challenge children to sit quietly in an area and try to get a bird’s attention by echoing its call. Record the noises you hear in the outside world and play these during quiet mindful time later on in the classroom.
*Create a musical wall by hanging recycled materials on a fence for children to explore - pots, pans, muffin tins, bells, metal pieces - and encourage children to create their own songs. These can be recorded as musical notations and ‘played’ by others. Encourage children to read other children’s music and play it using the materials provided.
*Provide a portable music source (wireless speaker, iPad) and encourage children to listen to and identify the different rhythms they hear. Add colourful scarves and other fun props to encourage big body creative movement incorporating patterning. Encouraging children to internalize and make emotional connections to the world around them using the five senses cultivates strong eco-stewardship and math learning. In addition to guiding children through the teacher-initiated games and activities listed above, there are many more ways to cultivate a mathematically rich and responsive learning environment in any outdoor space.

Puddle Play - Rethinking the 'Math Classroom'
How deep was the water? How much water was there really in the big puddle? Could it fill a bath tub? How could it even be measured?
Who could make the biggest splash? How would they even judge how big the splash was? Could it be measured? Was the biggest splash the one that soaked the most children standing nearby?
Could the water be used to make soup? How much water was needed in the recipe? Would anyone even want to eat mud soup?
How much water was in one's rain boots after a big splash? How long did it take to dump it out? How did all that water get in there in the first place?
How much more water was needed to cover the stump? Was the stump floating or sinking in the water? How tall was the stump? What if it rained more...would the stump be under water?
How long would it take to run across the puddle? Who could run the fastest over the water? How could we measure and record the puddle races?
