Use this resource to review family of facts for addition and subtraction. Use as a large group activity or a math center.
Students will find the “window cards” of addition and subtract to show the family of facts for the numbers at the top of the house. Once you add the correct answers on the back of the window or the back of the house, the center will be self-correcting.
Print the resource, laminate and cut the pieces. Store them in a large envelope and they are ready to use…for many years to come.
