This week’s #MathPhoto25 prompt is #even. Where do you see things that come in pairs? Where do even numbers show up in your world—on signs, in patterns, or in nature? #ITeachMath

Week 4 of MathPhoto25 is Even. Where do you notice balance and items grouped in pairs? Where do you see even numbers?

For those of you who are interested in seeing what a BTC lesson looks like, the Dutch BTC website has just posted some amazing classroom videos of Maarten Müller doing a convergent and a divergent lesson. They are in Dutch but the visuals are amazing. buildingthinkingclassrooms.nl/beeld-en-geluid/

I was digging through numbers in an architectural salvage store, and I couldn’t resist asking How many? #ITeachMath @triangleman.bsky.social @kassiaowedekind.bsky.social @simon-gregg.bsky.social @jnovakowski.bsky.social @pierretranche.bsky.social

Photograph of antique house numbers. There are three 7s, 1 one, two 4s, 3 eights, and 10 threes. The numbers have different styles and sizes, so students might count them in a variety of ways.
