Unit 6, Lesson 25# Solve compare with bigger or smaller unknown problem types.

EngageNY 60 min(s)

In this lesson, students strengthen their ability to recognize "compare word" problem types and solve for unknowns in varied positions. They also work with problem types that suggest the incorrect operation, such as, "Shanika went down the slide 15 times. She went down 3 more times than Fran. How many times did Fran go down the slide?" While students do not need to master this problem type in Grade 1, exposure to these problems contributes to students' long-term success.
