Collect one-half gallon milk or juice cartons. Place them in a position for bowling. Stand a few feet away and roll a ball to knock over the cartons. How many cartons were knocked down? How many left standing?
· One-to-one correspondence. Give each child an inflated balloon. Say: Each balloon needs a string. Provide the same number of strings as balloons.
· Equal sets. Provide modeling clay and golf tees. (A local golf course may provide these for your classroom.) Instruct children to make two circles with the clay. Use the same number of tees in each group.
