Montessori Subtraction Strips
Subtraction work based on the concept of the Montessori subtraction strip board, but simplified.
Two sets of number strips represent the numbers 1 through 10 and -1 through -10. The student chooses the two strips corresponding with his subtraction equation and layers the negative strip over the positive strip to determine the answer.
Instructions for preparation and presentation included in download. Color coded green to correspond with Montessori subtraction works.
