Balloon rounding
10052007, 03:00 PM


This is really late I know but I learned something really neat this year. We always underlined the number to be rounded and circle the number next to it. Then we ask does it round up to stay the same. Someone gave me the idea of getting a balloon. Hold it with all five fingers is a grip. Release one finger at a time, then ask does the balloon go up with 1 finger, the reply is no it stays the same. This continues until you release the fifth finger. Then the balloon goes up. Therefore 04 stay the same, then 59 round up. It was really neat and my fifth graders are now drawing little balloons instead of circles around the number next to the number that needs to be rounded.
