Understanding Area
Understand that a unit square has one square unit of area and that the area of a plane figure is the number of unit squares that cover it without gaps or overlaps
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Area measures the two-dimensional space inside a boundary in square units. For a rectangle, equal rows and columns connect area to multiplication.
Spend 10 minutes drawing two grid-aligned rectangles with whole-number side lengths, counting their unit squares, and connecting each count to length × width.

- Distinguish between area and perimeter as different measurements
“If your child counts the small squares inside a rectangle drawn on squared paper, can they tell you the area — and explain what "one square unit" means?”
