This packet contains 8 Christmas trees. Each tree is labeled with a number from 5 – 12. Ten ornaments are provided for each tree. There are 5 red ornaments with addition number sentences and 5 blue ornaments with subtraction number sentences. Students match the ornaments to the tree. The packet is organized so that it is easy to print only what your need for your students. Diversification is easy. Choose just the subtraction ornaments, just the addition ornaments or both. Choose the trees with the sums/differences that your students need to practice. This works well with small group or individual instruction, in math stations and in math centers. Laminate and use year after year. Created by Cheryl Litton and Greg Litton of Learning Harbor.
