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).
• 3.GSR.7.2 — Determine the area of rectangles (or shapes composed of rectangles) presented in relevant problems by tiling and counting.
• 3.GSR.7.3 — Discover and explain how area can be found by multiplying the dimensions of a rectangle.
• 3.GSR.8.1 — Determine the perimeter of a polygon and explain that the perimeter represents the distance around a polygon. Solve problems involving perimeters of polygons.
• 3.GSR.8.2 — Investigate and describe how rectangles with the same perimeter can have different areas or how rectangles with the same area can have different perimeters.
