Student use number knowledge of before and after, ten more, ten less, and number fluency within 120 to create a mystery picture. As the students fill-in the missing numbers on the pussle pieces, they will color the cooresponding squares on the 120 Chart. When completed, if done correctly, the colored squares will create an image. This is a Christmas Tree FREEBIE for you!
There are different images posted in my TpT store with more of these if you like this one! These are great for a center activity because students enjoy them while working on CC standard 1.NBT.1. I hope your students will enjoy!
