Tree Circumference

Students exercise their abilities in estimating and calculating circumference and subtraction. Teachers number 10 trees within the schoolyard and students then go outside to find each tree (1-10). First the students estimate each circumference, measure each circumference, and then find the difference between their estimation and actual circumference. Wrap up: Compare numbers, discuss which students had the closest guesses, etc.
