Associated Materials


    The 10-Box can be used to teach and reinforce the sequence of numbers by building a staircase from 1 to 10. This tool can also be used to teach addition, subtraction and problem solving within 10. Additionally, students use the 10-box to practice their combinations of 10 through activities and games.

    Learning the Combinations that Make 10- Finding Missing Addends
