Solving Money Word Problems Using Bar Models

MatholiaChannel

This educational video introduces students to solving money-based word problems using the Singapore Math bar modeling method. It presents two distinct scenarios: an addition problem determining the total cost of two items, and a subtraction problem calculating the price difference between two items. By visualizing the quantities as rectangular bars, the video helps bridge the gap between abstract word problems and concrete mathematical operations. The content focuses on key algebraic thinking skills appropriate for early elementary students, specifically distinguishing between "part-whole" relationships and "comparison" models. It demonstrates how to translate text into visual diagrams, identify the unknown variable (represented by a question mark), and select the correct operation (addition or subtraction) to solve the problem. For teachers, this video serves as an excellent tool for modeling mathematical thinking. It can be used to introduce the concept of bar models, reinforce strategies for solving word problems, or support students who struggle with determining whether to add or subtract. The clear, step-by-step visual progression makes it particularly effective for visual learners and for scaffolding complex problem-solving skills.
