Day 69: Is it a Square?


As it was with the rest of the unit, so it continues.

We do some work around trying to figure out whether shapes are squares or rectangles, ideally with coordinate geometry. But to start, we look at whether or not a shape is a square or rectangle as a shape (without coordinates).

Some fascinating conversations here. I wish I could have recorded them better. I also wish we had done this as a sort.


Day 68: The One where We Review Area


To prepare for using coordinate geometry to find area and perimeter, we have to review area and perimeter. This is a nice chance to catch up the kiddos that weren’t here at the beginning of the year and review for many more kiddos who maybe didn’t fully understand the first time. It’s also a fascinating exercise into how long kiddos will draw boxes before using the base times height shortcut.
