What Is Area?
Cover a rectangle with unit squares, with no gaps or overlaps.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 70
- Welcome to Area and Perimeter Park! Area is how much space a flat shape covers. We measure it by covering the shape with squares that are all the same size.
- The squares can't leave gaps. Then some of the space isn't counted.
- And the squares can't overlap. Then some of the space is counted twice!
- Your turn! Tap each square to count it.
- 12 squares cover this rectangle, so its area is 12 square units.
Georgia's K-12 Mathematics Standards:
- 3.GSR.7.1 — Investigate area by covering the space of rectangles presented in realistic situations using multiple copies of the same unit, with no gaps or overlaps, and determine the total area (total number of units that covered the space).
