The workbook "Using Bar Models: Addition and Subtraction" continues practice to help students understand how to visually represent and solve addition and subtraction problems using bar models. This involves teaching students to translate word problems into visual bar diagrams. Using this workbook, students practice using bar models to solve real-world problems, compare quantities, and understand the inverse relationship between addition and subtraction.

Bar models are pivotal in helping students visually conceptualize addition and subtraction problems, offering a clear representation of the relationships between numbers. Students can more easily understand how numbers combine and separate by illustrating parts and wholes through segmented bars. Bar models encourage students to develop strategic thinking.
