Students need to get into groups. Each group needs a spinner and a place value chart through billions. One student spins the spinner and all the students in the group write the number in their chart. Once you put the number down you can’t move it. Continue until the entire chart is filled in. Discuss who has the largest number in the group, how you know, and whose number is the closest to the largest.
