I'm looking over mathematical openers in preparation for a talk, and WOW - if you don't use these, you're missing out.
Here are my 3 favorite websites for (free!) resources:

Lots of images for my favorite talks, chats.
Plus opening games and more

I'm genuinely confused about this. #PrimeClimb, A MATH GAME, has somehow become the 15th most popular board game Amazon sells.
Am I crazy? Is this normal? Or is the needle moving?

Just found out my talk made the @TEDTalks main site! I have no idea when. And the name got changed!
Mixed feelings on that part, though presumably they know the audience better than I do. Still, exciting!

Let's take a moment to appreciate the power of manipulatives for visualization.
Imagine the hexagon is our unit. Then the first tower represents "3 and a half."
What do the others show? The same quantity, but with different names.

If you're choosing curriculum for a summer program, I implore you to go with a play-based approach.
Students don't need to suffer to learn math.
In fact, when they're engaged and playing, they learn more, and more deeply.

Maybe if we indicated that numbers go above and below it. We could put dots to show where the numerator and denominator go.
I mocked up a good replacement symbol, with a dot above and below the fraction bar to indicate where the numbers go...

A friend just texted me this conjecture. I think it's a great one for students to try to prove/disprove!
One counterexample where 0 isn't possible would disprove it. But does it exist? Or is the claim sound?

I suspect the intention is, “what could the five numbers be?”
Potentially an excellent question! And hopefully students will notice that there is more than one answer, and handle it as necessary.
A possible extension: what’s one more condition that would make the set unique?
