This video shows the "Modeling" method for solving subtraction problems. This strategy is great for students who are moving from concrete learning (using manipulatives) to more abstact learning. In this method, students draw pictures to represent the highest number, then begin taking away the smaller number. Children can "see" the steps of traditional regrouping. This helps build number sense because students are visualizing the base ten representation of numbers. This is not the most effecient means to solve a subtraction problem, but it effective. One word of caution - your child does not have a "picture" to use for numbers larger than 4 digits.
