Teaching Geometry
What it is
Perimeter and area of rectangles, by counting squares and from labeled side lengths, and a rectangle to draw that has a given perimeter or a given area.
When a child is ready
Ready once multiplication facts are known and the child adds four numbers.
If they struggle
Keep the two apart: perimeter adds the four sides, area multiplies length by width. Have the child say which one is asked for before starting.
