These addition and subtraction puzzles are great for math centers or early finishers!
I print mine on cardstock, laminate them, cut them apart, and then give the kids a dry erase marker and they are off to work!
The squares have to have the same number & the circles have to have the same number. Both equations have to be true. It is a great way to practice addition and subtraction & to get at those higher level thinking skills. My kids LOVE when they figure out a puzzle!
