10-20 Number Comparison Game
Build number comparison skills (more than/less than) while your students work together at math centers.
This game is played the same way as the traditional card game “War”. The "Top Dog" is the one with the most cards when the center time is over, although my students play this happily without needing to know that there can be a 'winner'.
Differentiation is easy depending on individual student skill levels! Students can count the number of bones on their cards, they can tell (and record for an added skill level) how many more bones are on their card than on their partners, etc...
