This is a set of puzzles for the numbers 10 through 20. Each puzzle consists of five pieces. The middle piece is the number. Then around the middle piece are four different pieces, each representing the number in a different way: ten frames, ten sticks and ones, 10 + __, and tally marks.
I created this to help my students master K.NBT.A.1. I feel that this is a difficult standard to master, so any additional help is beneficial for my kids. I hope you find this helpful! :)
