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.

Building a Curious and Playful Early Childhood Math Community
Toni Cameron and Deanna McLennan in conversation with Stenhouse’s Kassia Omohundro Wedekind about creating a supportive, curious, and playful environment for mathematics in early childhood classrooms, the importance of stepping back to listen, and (of course!) what this all looks like these days.

Cultivating a Mathematically Rich Learning Space
It's almost Labour Day! This time of year always fills me with hope. Although
it's sometimes sad to be leaving the fun and comforts of summer -
spending time with my children, sleeping in, enjoying the back yard with
my pup - it's exciting to think of the possibilities of another school
year. Like a blank canvas waiting to be painted our classroom evolves
and changes over time as the children and I learn and explore together.
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 thought it would be easiest to create this as a 'math check list' with
points to read and consider. 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 return soon to our classrooms with open eyes, minds and hearts.

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?").

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.
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.
These are just a few of the ways in which I cultivate a rich math space with children. I'd love to hear from you! Share your math ideas in the comments below, and consider following my Instagram @McLennan1977 for regular ideas from my classroom!

Creating a Space that Cultivates Math Learning
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. 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 list isn't all inclusive, I thought it might spark some ideas to support and inspire as we enjoy the first weeks of school and start back in our classroom with open eyes, minds and hearts this month.
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.

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.

A Classroom Tour for September
- children are capable of constructing their own learning
- children form an understanding of themselves and their place in the world through their interactions with others
- children are communicators
- the environment is the third teacher
- the adults in the room are mentors and guides
- there is an emphasis and importance on documenting children's thoughts and experiences
- there are hundreds of languages of children and these are used to explore and communicate ideas and experiences

Above each child's cubby is a recent photo and painted self-portrait. These change a few times each year (usually a new photo and self-portrait per term) to help show their growth. We like including a real photo to celebrate each child and love how the children use the language of art to represent their perception of self.
Our drama centre changes based on the interests and requests of the children. At the beginning of the year it is set up as a little 'house' to provide comfort and familiarity to children. We include many real objects for the children to use in their imaginative play; real objects communicate the message to children that they are capable of using these tools and make the context for the imaginary play very real and meaningful. Donations from families and the local community also helps represent the diversity of our population and encourages children to see themselves and their peers reflected in the space. Literacy is interwoven throughout as children can talk on the phone, write on the chalk boards, or follow a recipe when cooking. A variety of scarves encourages children to dress up and create their own costumes and clothing. A large basket of fabric flowers can be turned into different arrangements for the table or inspire other dramatic play (e.g., a flower shop, a farmer's market).
Our building area is the heart of our room and the most popular place to be. Children integrate materials from all around the classroom into their play here. We love the big body play the wooden blocks encourage. Small loose parts (e.g., tile squares, corks, wooden spools) are also included in this area for children to combine with wooden blocks. Pillow are available for incorporation in the creations and photos of local structures are displayed for inspiration.
My favourite center in the classroom is the science area. We are fortunate to have a very large wall of windows on one side of the space. The shelf near the window houses materials that are specific to ongoing inquiries. Loose parts play are a big part of our program as we embrace all things STEAM and love our makerspace. We use many natural and found materials here and always welcome donations from our families. The science area also houses many building materials and the children can freely use these around the room in any area to support their play. Often treasures found outdoors (e.g., pinecones, feathers) and the changing of the seasons inspire inquiries. Invitations for further exploration are sometimes set up on the table in this area. A sensory table integrates imaginative play regarding current interests, here insects and their natural habitat. Children can swap out materials for other small world play (e.g., dinosaurs, fabric flowers).

The art studio is located in a sunny area of the classroom. You can see that colours and colour mixing are ongoing interests and there is much art that supports this. The materials are aesthetically arranged to be accessible for children and also decorate the space. Materials are organized by colour for ease of accessibility and also to embed math and sorting into the centre.
We are often asked by other educators about how we encourage the children to engage in regular reading and writing in a child-driven space. On the back of our bookshelf are writing clipboards, one per child. We ask children to self-select a piece of writing that they are proud of and display it on their clipboard. These are then brought to a sharing circle where children can discuss their work with others. It's a quick and easy way for us to see which children have (and haven't) engaged in regular writing so we know how to better support their needs. This clipboards can also be brought on nature walks in the yard or community as needed.
