Unit 7, Lesson 20# Solve two-digit addition and subtraction word problems involving length by using tape diagrams and writing equations to represent the problem

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students use drawings to compare lengths and write equations with an unknown to represent problems. They solve two-digit addition and subtraction measurement problems using customary or metric units, composing or decomposing a ten if necessary. They also compare lengths using the tape diagram, essentially a horizontal bar, to solve two-step problems.
