This slideshow was used as part of an introduction to perimeter in a 3rd grade measurement unit.

1. YARDLEY

2. Perimeter is the measure of a distance around a shape or closed figure! 60 yards 60 yards 100 yards 100 yards

3. 60 yd + 100 yd + 60 yd + 100 yd = 320 yards So if I wanted to put white tape around a soccer field, I’d need 320 yards of tape to get all the way around it! 60 yards 60 yards 100 yards 100 yards

4. Yardley has a great backyard to play in – but he wants to have it all to himself and keep other animals out. So his owners decide to build him a fence. How do his owners figure out how much fencing they need? YARDLEY

5. Yardley’s backyard is 10 meters long and 5 meters wide… So his owners should add ____ + ____ + ____ + ____ 10 m 10 m 5 m 5 m YARDLEY

6. 30 m of fence! PERIMETER OF BACKYARD (distance around it) = 30 m YARDLEY

7. Thanks for fencing in Yardley! Now let’s try another challenge at… MATH SPY GUYS! These kids sure know perimeter! YARDLEY
