Perimeter is what I know — round and round and round we go!!
Okay, and I know how to make animated GIFs tho’ I don’t know how to add sound to them (yet). BEcause yes, I want them to recite at you 🙂

It’s the “hint” for a lesson on finding the missing piece in the perimeter of an “L” shape.
The “big idea” of the course that’s based on is “parts and wholes,” and the idea that a significant chunk of people who struggle with basic number sense got dropped off the math wagon before they figured out that when you figure out “5 + 3 = 8” that the five and three don’t go away.
I like it much better as an approach for figuring out word problems than Looking For Key Words. Are you looking for a part, or the whole thing?
