Five pages that put area and perimeter side by side, so students learn to tell them apart. Pages 1 and 2 find both measures, first for shapes on a grid and then for rectangles with side lengths. Page 3 shows pairs of rectangles with the same perimeter and different areas. Page 4 has students draw two rectangles with a perimeter of 12 units, then two with an area of 12 square units. Page 5 lists ten everyday jobs to sort into area or perimeter.
Give pairs of students 12 square tiles and ask for every rectangle they can build; record the perimeters on the board. Then use string loops of the same length to make rectangles with different areas, which sets up pages 3 and 4.
Ask which measure fits a job around the house: covering a table with a cloth (area) or putting tape around its edge (perimeter).

A 5-page area and perimeter pack for 3rd grade. Find both for shapes on a grid and for labelled rectangles, compare rectangles with the same perimeter but different areas, draw rectangles with a given perimeter or area, and decide whether a job needs area or perimeter. Answer keys included.
