Almost every day, the students take laps around the triangle outside our classroom door. This week, I wanted to know the perimeter of the triangle. I asked Teacher Elyse to take a few kids out with yard sticks and chalk to measure it. It turns out that that the perimeter was 140 yards. I showed the kids how to convert the yards to feet. Then, we used fractions to figure out how many miles one lap equaled. It turns out that one lap was 8/100 of a lap. From this calculation we were able to figure out that it would take 12 1/2 laps to equal 1 mile. Now we can start keeping track of how many miles we run each week. Neat!
