Instead of taping a multiplication chart to the desks of elementary students tape this beautiful image from Dan Finkel Let’s have them think like mathematicians! #edchat #mathchat

A favourite puzzle-

Just got a pretty interesting new prototype we've been working on in the mail. Should be available around September, for those who've been asking 🙂

Here's a simple technique that will get your students talking more about maths- (And will launch an entire lesson) It's called: "Which is larger?" A 🧵

When subtracting from a number that ends with a lot of zeros, consider subtracting 1 from both numbers so we don't have to "borrow" several times.

This was a life changing book study for so many of our participants! Can’t wait to read the next book!

When your day starts with the humble honor of teaching with the amazing nate balk, you know it’s going to be an INCREDIBLE day! Thanks, Nate!

Can’t wait til mine arrives!

Here's how we can visually show why "keep change flip" works:

I wish I was taught this way of finding the greatest common factor when I was in school

An all-time favorite lesson just got added to our free lesson library!Featuring 21st Century Pattern Blocks. Pattern Block Scaling - mailchi.mp/mathforlove/ne… #iteachmath #mtbos Christopher Danielson Hana Murray

How can we visually show why something like sqrt(90)=3sqrt(10)? Rewriting square roots can be seen visually! (I know the title doesn't sound appealing but I honestly really like the concept lol)

A neat puzzle- 1. Shade any 2 sections 2. What fraction of the square is shaded? 3. What other fractions are possible? Impossible? This puzzle kicked off discussions at a workshop for PD Hub members.

Teaching tip: Here's how I spice up the activity "Which One Doesn't Belong?"

We don't HAVE to rely on (or go straight to) "two negatives make a positive" when subtracting negatives. Here are two visuals I recommend when learning this concept.

It's Mental Math Monday with guest Mike Flynn! How would you mentally calculate 11+12+13+14+15?

Beautiful BTC session given by Tracey Bean for 60 teachers! Thank you Team Wipebook for the materials for a successful class!!
