This lesson covers estimating products. Students learn to estimate a product or quotient by first rounding each number to one non-zero digit. For example, to estimate 8,291 x 27, first round 8,291 down to 8,000, and round 27 up to 30, then multiply 8,000 x 30 to get 240,000.

This lesson covers perimeter. Students learn that the perimeter of a figure is the distance around the figure, so the perimeter of a figure can be found by adding the lengths of its sides. Since all four sides of a square are equal in length, the perimeter of a square that has a side with a length of 8 feet is 8 + 8 + 8 + 8, or 32 feet. Since opposite sides of a rectangle are equal in length, the perimeter of a rectangle that is 4.5 meters by 6.2 meters is 4.5 + 4.5 + 6.2 + 6.2, or 21.4 meters.
