Don't Be a Turkey!

One of the Common Core Standards for second grade math is:

CCSS.Math.2.OA.2 Fluently add and subtract within 20 using mental strategies.

This game works like "Old Maid", so they pair off all the addends with nines and sums, and one of your little turkeys will end up being the "Thanksgiving Turkey".

This is one of those games that "even the losers are winners" because there's something about cooking a turkey that makes the little ones giggle.  Plus, they're getting better at that mental math!

When they've mastered the plus nines up through 20, there's a more challenging version of the game to work this standard:

CCSS.Math.Content.2.NBT.B.8 Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.

Have fun practicing mental math, and don't be a turkey!  (At least, don't be a cooked turkey!)
