This center/activity has three different recording sheets that students can play. The first has only 10 more or less, the second has only 100 more or less, and the last has both 10 and 100 more and less. Students draw a card and write the number in the center column of the recording sheet and find 10 or 100 more and less. There are 18 number cards in this activity. Some of the numbers do cross centuries (hundreds).
The three different sheets make this an easy activity to differentiate. You can also differentiate by taking out the numbers that require students to cross the centuries for those who are not ready for that skill.
You can turn this into a collaborative center by having the students pair up and take turns drawing a number. The partner can check to make sure the student writes down the correct answers.
