Headline Story
John wants to measure the area and perimeter of _____. He needs help.
Possible student responses
- John could measure the top of a rectangular table (the area) and the edge around it (the perimeter) using a ruler.
- He might measure the sides in inches or feet and then calculate the area in square inches or square feet.
- John could use rope to measure the perimeter of a small, round pool, and then measure the rope by matching it up to a yardstick.
- Figuring out the pool’s area would be harder, but John might make a rectangle around it, find the area of the rectangle, and then subtract some to make an estimate.
