How do you teach subtraction with regrouping?
Teaching regrouping in subtraction can be a challenge at the least. It is a difficult concept for many students to visualize and really grasp. Even when the concept is mastered, regrouping easily lends itself to simple mathematical errors in the early grades. However, the right teaching and learning strategies can make regrouping much quicker and easier to master. To teach subtraction with regrouping, first verify that students have learned and mastered the underlying concept of subtraction and place value. Students may be able to memorize the steps in regrouping, but they will not be able to understand what they are doing and really apply it correctly unless they fully understand the representations involved in place value and why and how numbers are exchanged between the places or positions of numbers. Once students have mastered these concepts, teaching and learning regrouping will be much easier. Provide manipulatives or visual representation of numbers. Even if students understand
