Mean Girls but it's a movie about Cady learning the different types of mean.

Cady Heron from Mean Girls looking at 3 mean girls and each of the 3 are labeled a different type of mean (geometric mean, arithmetic mean, harmonic mean).

If chicken nuggets only came in boxes of 6 and 7, what's the largest order not possible?

1 4 27

Howie Hua @howiehua.bsky.social · 7d

That's because the largest order not possible is mn-m-n, which matches your (m-1)(n-1)-1.

How high can we lift the string?

If you are teaching the Pythagorean theorem, I highly recommend this problem!

When dividing by a fraction, a lot of people think about the measurement model, but we can think about the partitive model too! Here's why I think the partitive model is powerful.
