Lesson 2. Unit 2. Grade 7 EngageNY

EngageNYVaries

This Problem Set is a part of the Lesson 2, Unit 2, Grade 7. Students model integer addition on the number line by using horizontal arrows; for example, an arrow for -2 is a horizontal arrow of length 2 pointing in the negative direction. Students recognize that the length of an arrow on the number line is the absolute value of the integer. Students add arrows (realizing that adding arrows is the same as combining numbers in the Integer Game).
