To work on your student's basic addition and subtraction skills, your student will match the number cards to its corresponding word problem. The colors on it match the colors of the Montessori colored beads. This can be used with Pre-K to 3rd grade aged children as a center, independent work for homeschooling, or as a one on one activity with a teacher/parent.
