Unit 1, Lesson 28

Solve take from with result unknown math stories with math drawings, true number sentences and statements, using horizontal marks to cross off what is taken away.

EngageNY 60 min(s)
In this lesson, students solve action-based "take from with result unknown" problems, as they start with a set of objects, then take some away, and finally end with a smaller set of objects (for example, "There were 6 children at the sleepover. 2 children got picked up. How many children stayed?"). They work with simple math drawings and equations to represent these stories and connect the act of crossing off to the symbol for subtraction.
