Building Thinking Classrooms is a great way to make math collaborative & engaging! Not only do students ask for a BTC, but they truly enjoying sharing their thinking and teaching one another their strategies!

New year, late start to posting! Our Gr 3/4’s were excited about our new subtraction practice! We build 5 tens using pipe cleaners and beads. We write 50 at the top and roll two 6-sided dice and subtract the total by moving the beads. What if we don’t have enough beads on a group of 10? We borrow!

We finished our Gr3 #EQAO today. During the questionnaire my students were shocked by “the rudest question ever!” The statement said “Only certain people are good at math.” The gasps & outrage echoed through our room… ♥️ I’m so proud and thankful that a group of kids know ANYONE can be good at #math!

When your students know how much you love teaching math ♥️🧮 #matheducation #scdsb #probability

David was my last presentation at OAME and made me truly stop and think about what kind of questions I provide students. Then he dropped the ultimate teacher freebie: the New Daily Cumulative Review! I cannot wait to share this incredible resource with my colleagues today! #OAME #scdsb #math

I had planned to share all of my sessions but the two days went by so quick! All teachers should get to experience #OAME! A few highlights for myself was listening to (the greats) Jo Boaler, Marian Small, and Alex Lawson, and experiencing my first time as a presenter as well! #matheducation #scdsb

I’m looking forward to chatting #math with educators attending #OAME2025. I’ll be talking about problem solving, metacognition and a literate environment this afternoon.

I’ve made it to my first session at #OAMElearn and cannot wait to begin! Starting off with the incredible Alex Lawson, Mel, Kate, and Heather to explore Celebrating Students Natural Thinking: Accessibility and Effective Way Forward in Multiplication and Division! #ontariomath #scdsbmath

#cuisenairerods are an amazing way to explore math! My Gr 3’s were encouraged to create math talk images today during our small group deliberate practice! Our room was filled with oohs and aahs! What do you notice? What do you wonder? #scdsb #math #primarymath #teaching #scdsbmath #mathcenters

Our #mathstoday was reviewing Ms. Watson’s @timhortonsofficial.bsky.social Roll Up Tally!! While my class was positive I would win a car, we were excited to see some “rare” winnings pop up! But Ms. Watson has been enjoying all her free drinks! Thanks Timmies for the math fun!

I love my students excitement for Math Centers! But when one says “I can’t wait to see fractions in centers”, I can’t contain my excitement! Games, puzzles, & math journals were all a hit! Check out how they organize their thinking #mathstoday #scdsb #oame #mathcenters #mathfun @eduskyteam.com

Things to focus on when you feel out of control:

For the first time ever I’ll be presenting on my love of Math Centers! I’ll be at the #oame conference this year, alongside some of the most inspiring math education enthusiasts — @natbanting.bsky.social @mathematize4all.bsky.social @markchubb.bsky.social @joboaler.bsky.social and many more! #scdsb

It’s happened. I am officially pro #kindle! I never thought I would turn my back on paper books. However, after being gifted a #kindlepaperwhite, I’ll never go back! I’ve read seven books in 2025 so far, while also discovering new genes thanks to the easy search and purchase options #reader #reading

Me: I'm a math teacher. Them: Oh, I hated math in school. Also, what's with this new way of teaching math? Why don't they just teach it the way we were taught? Me:

I just posted a new Problem of the Week! This week’s focus strand - Spatial Sense (Measurement and Geometry). Click here costellomath.com/problem-of-t... #math #elemmathchat #edusky #mtbos #iteachmath

Looking for an easy way to engage students in small groups? Two words: smelly markers! We are learning multiplication & creating arrays in Gr 3. Even my most apprehensive students begin to relax! #scdsb #math #elementaryschool #smellymarkers #ontario #education #teaching #teacher #mathematics

We enjoyed sharing ways to bring curiosity back into our classrooms at the #mead2025 conference. Check out our link tree for resources: linktr.ee/nurturingmat... @jodyguarino.bsky.social

Inspiring #acadience training hosted by #scdsb literacy team today! My professional goal for the next two months is focusing 5-10 minutes a day on a fluency routine in our classroom. Data driven instruction leading the way! #literacy #assessment #education

It's Mental Math Monday with guest Eric Bill from Southern Tier New York. How would you mentally calculate 1+2+3+4+5+6+7+8+9? #math #ITeachMath
