I use math centers everyday usually either at the beginning of my math block for 10 or 15 minutes or at the end. I have the 6 groups posted and rotate the centers around their names each day. During a 3 week period, I use
the same centers, then I try to rotate in 2 or 3 new ones in. The games are simple to make, I run them on cardstock and laminate them. One of the games I bought is a simple card game I got at Target or Walmart called BLINK and another is Qwitch. They cost only $4.99 but the kids absolutely love them. There is a older book I found on Amazon I heard about at a math workshop called, Math
For Girls. It is for boys and girls but it worth it just for the simple math games that you can find in it. I have also used some of the ideas on Mspowell.com. If you need any copies of anything, feel free to e-mail me. I can put things in Publisher or Word for you. Best of luck to you. lharing@nlsd122.org
