In previous lessons, students learned how to measure lengths using different units of measure. In this lesson, students solve Take From problems involving length measured in inches. They use the context of length to make sense of tape diagrams that represent the part-part-whole relationships between the quantities in each story (MP2). They also continue to practice adding and subtracting within 100 with and without decomposing a ten.
