My math center packet comes with 10 worksheets. My students do math centers when we are done with the lesson. I keep the worksheets in a file box. The supplies (cards, spinners etc.) are kept in labeled tubs.
-Deal it: add and subtract. You will need cards for this, A-10. I have more than one deck so multiple students can use them.
-Spin it: add and subtract. You will need a spinner with numbers. I use 0-10.
-Domino Math: (2 versions) add and subtract. This you will need dominos.
-Fact Family: I let them use dice to roll for the numbers.
-Ten Frame: they can use crayons, markers, pencils etc.
