  8. Area = Base x Height A B 10 feet D C 20 feet

  9. Does It Measure Up? • Now its your turn… • In small groups, the class will be surveying an area of the playground. • To do this, each group will need two pieces of sidewalk chalk, a Gunter’s chain, a pencil, and a copy of the “Does It Measure Up?” worksheet. • Sketch a picture of the area that includes landmarks such as the slide, swing set, etc. • Measure the distance between the boundary markers determined by your surveyor • Once you have completed the measurements, your group will be computing the area and the perimeter of the land you surveyed.
