LOVE this site! It's for upper elementary, and gives supplies and procedures for playing math games in the classroom. Simple, but very effective! Nine games are included.
There are LOTS and LOTS of games here! Logic games, word problem games and much more!
This one is called "Space Raider X"
This one is called "Cash Out" and comes in easy, medium and hard.
If you haven't found Cool Math for Kids yet, do it now! It has lessons (yes, lessons) and games. Great for remediation or extension!!
If you want a great spot to find LOTS of great math ideas and freebies…this is the spot!
One of my favorite game sites…these games are lots of fun and SOOOO full of learning!
