We're just days away from Teachers Pay Teachers' giant Christmas in July sale and Santa's on vacation to rest up for the rush. Since he's busy drinking Pina Coladas under a palm tree, I'm stepping in for Santa and sending you a little present. It's a math center where the kids have to match the Santa addition cards with the flip-flop cards that have the matching sums. Just click on the picture to download. Check back in tomorrow for the list of all 34 sellers participating in the TPT Christmas in July sale!
