Unit 4, Lesson 8
Equations on a Number Line
Grade 2
Preparation
Lesson Narrative
In the previous lesson, students interpreted representations of addition and subtraction equations on a number line. They used the direction of the arrow to determine what operation was represented and matched equations to number lines.
In this lesson, students write equations based on number line representations and represent given equations on number lines.
- Representation
- MLR8
- Create equations to represent number line diagrams that show addition or subtraction.
- Represent addition and subtraction on a number line diagram.
- Let’s write equations and represent them on a number line.

Teacher Reflection Questions
What evidence have students given that they understand the connection between the number line and written equations? What questions did you ask to make the connection more visible?
