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.

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.

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)

2 years ago, I received a 17 page Google document of teachers who participated in a book study for Chasing Rabbits in Colorado. Sometimes, you have no idea as to the power of the words you put together. @HumResPro @eureka_math

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.
Top: Spongebob looking stressed. 10,000-4,289 with the "borrowing" method. Bottom: Spongebob looking cool, snapping fingers. 10,000-4,289 turns to 9,999-4,288=5,711

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 🧵

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 🙂

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