These cards add up to math success! Kids can build their addition skills by completing the equations on each colourful write-on wipe-off card. Just one quick sweep of the pen's eraser and the marks are gone so you're ready to practice again. Because the cards are colour coded to indicate difficulty, kids can work their way up as they master harder and harder problems. The pack includes 40 cards, plus a pen.
