Students will be anxious to show you what they can do with rounding numbers to the nearest 10 or 100. The center can be used in two ways: 1. Students will round the number to the nearest 10. 2. Then they can idround to the nearest 100 using the same set of cards. There is a student answer sheet and answer key for both of these centers. You can also use the cards for a whole group activity.
