Mastering Subtraction with the Make-a-Ten Strategy

MatholiaChannel

This educational video introduces young learners to the "make-a-ten" (or bridging 10) subtraction strategy, a fundamental mental math technique. Through three distinct examples, the video demonstrates how to break down subtraction problems into two manageable steps: first subtracting to reach the friendly number 10, and then subtracting the remainder. The progression moves from concrete visual aids (toy cars) to semi-concrete representations (blocks), and finally to abstract numerical notation, scaffolding the learning process effectively.
