In This Unit of Study…

Students solve perimeter and area mathematical and real-world problems, including problems with unknown sides, for rectangles with whole-number side lengths. They also investigate problems involving rectangles with the same-size perimeter and different-size areas or with the same-size area and different-size perimeters. Problems involving multiplication are limited to products of up to 3 digits by 2 digits, and problems involving division are limited to up to 4 digits divided by 1 digit. When calculating area and perimeter, it is the expectation that students express the appropriate units in word form.
