Unit 2, Lesson 2# Express metric mass measurements in terms of a smaller unit; model and solve addition and subtraction word problems involving metric mass

EngageNY 60 min(s)

In this lesson, students apply their place value understanding to compare and convert grams and kilograms. They build an understanding of the relationship between mixed units containing grams and kilograms and then apply this understanding to add and subtract masses using the standard algorithms they learned in the previous unit or using simplifying strategies. The lesson culminates with students applying this learning to solve a one-step word problem with multiple decompositions.
