The target group of students are 17 second grade students who are labeled as one grade level below in number and operations, ages 8-9. Students entering second grade should understand that a two-digit number represents amounts of tens and ones. Also, when given a two-digit number, students should be able to use concrete models or drawings and strategies to add or subtract multiplies of ten. The targeted students are unable to fluently subtract within 100 based on place value.   Contributing Factors to the Instructional Problem  A possible factor seen on homework contributing to this problem is parents pushing the traditional method of subtracting two-digit numbers. Most parents of these second graders were taught to line up the two numbers vertically and borrow one ten to give to the ones when needed. This procedure works but students dont conceptually understand the exchanging of place values. In fact, Flores, Hinton, and Strozier state that “often, students who struggle memorize algorithms or number combinations and fail to grasp the underlying concepts that are required for future learning (2014).” Children lack the ability to explain the algebraic thinking and reasoning of regrouping and th
