With the help of one of my Kindergarten students, I have created a "Go Fish" type game with a holiday twist - Go Snowman! And the cards give your students a little bit of a challenge.. once they pick a card, they have to do the subtraction problem. They play just like "Go Fish" and ask the friend if they have a 4 (if their card is 5-1 for example) and if a student has a card that says 9-5, that equals 4, so that's a match! I hope your children enjoy this holiday version.. there are 24 cards total with matches 0-12. Let me know if you have any questions before purchasing this product!
