Unit 1, Lesson 18

Solve multi-step word problems modeled with tape diagrams, and assess the reasonableness of answers using rounding

EngageNY 60 min(s)

In this lesson, students apply their learning from Module 1 to solve multistep word problems using tape diagrams, the standard algorithms for addition and subtraction, and rounding to assess reasonableness of their answers. Students extend their thinking from one- and two-step problems in the previous lesson to multistep (three or more steps) problems in this lesson.
