rounding activities
By kathleen

For rounding to tens, I use a hundreds chart. Students place a chip on a given number, then move the chip to the closest tens. The other activity I've done is using some type of manipulatives, such as macaroni or buttons. They put a certain number of buttons in the center. Then they count out how many they would need to round up and place on the right hand side in a group, and count out how many to round down and place to the left. They find that the side with the less noodles is the way they round. That is a real beginning rounding activity.
