This math center is perfect for practicing addition. If your students are like mine, they'll love it! They will figure out the answer to the addition problem, then clip a clothespin the the right answer. Simply print, cut, and laminate (if you want). I also put a smiley face or sticker behind the right answer.
I also have a Spring Addition Clip-it set and a full set that includes the Spring set, plus sea animals, the monster set, and several other pages!
