If you’re needing something quick and fun (and you have a Smart Board), I have two free Smart Board games. One is for comparing numbers on the kindergarten/1st grade level.
The other is for comparing decimals on the 4th-5th grade level.
Both use a fun Santa self-checking feature that your students will get a kick out of. If you don’t have a Smart Board, but you do have an interactive whiteboard, you may be able to still open the games through the Smart Express site.
If you need math Smart Board games, please check out the full FlapJack selection. All games are self-checking with fun themes that will keep your students engaged in math centers (and whole group) all year long. 🙂
