Grade 3 - Word Problems - Bar Modeling for Comparison Word Problems

In this video, we'll explore how to solve a word problem involving comparison using bar modeling, a visual strategy commonly used in Singapore math. The problem involves Tanner and Scott, where Tanner has three sets of blocks and Scott has one set, with Scott having 124 fewer blocks than Tanner. By using bar modeling, we'll break down the problem visually to understand the relationships between the quantities.

We'll then use division and multiplication to find the total number of blocks they have together. This approach not only helps in solving the problem but also strengthens the student's understanding of the relationship between the quantities in a comparison problem.
