This is a great math center game which can be edited. It has 20 cards for 10's, 20 cards for 100's, 20 cards for 1,000's, and five blank cards.
I suggest that you copy on card stock, laminate and cut each card into four. This will create 3 sets of 20 and 20 blank cards. I put clothes pins with this game, but you could add a dry erase maker instead. There is also a guide page that the students can use.
