Property
A tape diagram models multiplication by showing a total broken into equal groups. The relationship is:
In this Grade 5 enVision Mathematics lesson from Chapter 3, students learn to solve multi-step word problems involving multiplication by drawing bar diagrams, defining variables, and writing equations. The lesson covers real-world scenarios such as comparing quantities using "times as many" language and finding unknown products with multi-digit whole numbers. Students also practice using estimation to check whether their answers are reasonable.
