Rectangles and squares — 2nd grade math lesson
I show how we can measure the "size" of rectangles and squares: we check how many "little squares" fit inside them. Can you, for example, draw a rectangle with 15 little square inside? How about 16? Can you do that in several different ways?
This is of course preparing students for the important concept of AREA, which they will officially learn in 3rd grade.
Beyond that, we "play" with two different geometric PATTERNS that consist of rectangles and squares.
