Lesson 19. Unit 6. Grade 1 EngageNY

EngageNY10 min(s)

This Problem Set is a part of the Lesson 19, Unit 6, Grade 1. In this lesson, students share their preferred addition strategies, explaining the reason they choose to use a particular strategy for a particular set of addends. For instance, when adding 39 + 43, one student may prefer to use the "make ten" strategy, decomposing 43 into 1 and 42, because adding 40 + 42 is an easy problem for her. Another student may prefer vertically aligning the numbers to ensure that he is adding ones with ones and then tens with tens.
