This is a racing themed rounding spinner activity. It comes with a spinner number card that you would laminate. You can then add a metal brad and paperclip to turn it into a spinner. The students would then work by themselves or in a cooperative group to complete the activity. They spin the spinner to make numbers to the ten-thousand's place. They will then round those numbers to the specified place, from ten's to ten-thousand's. In order to extend the activity, you can copy the activity on the front and the back of the paper. This activity is suitable for a grade.
