Listen to Pam Harris and Kim Montague and start mathing in your classroom bc Ss should be thinking and reasoning about math. #MathIsFigureOutAble #MathStratChat
Check these fantastic contexts to help reason about this problem! Nice!

The golden ratio is a special number approximately equal to 1.618 that appears many times in mathematics, geometry, art, architecture and other areas.

Pam Harris Then one more question. You are to make one cut (or draw one line) โ of course it neednโt be straight โ that will divide the figure into two identical parts. (By Martin Gardner ) #mathStratChat #mathpuzzle #challenge

Pam Harris Initially I thought of Kim Montague and 25% being close and using quarters. Then I played with factors as I like finding 11% of things

Last week I learned from Danika Murray to scale down to scale up! I immediately noticed that half of 27 is 13.5 and if I scaled up, I could get close to 1323! #mathstratchat
Pam Harris Diff of squares:
(40 - 6)(40 + 6) = 1600 - 36 = 1564 #IHYN
Also, I can use an Over Strat (see pic)
