In the previous lesson, students interpreted representations of addition and subtraction equations on the 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.
Activity 1: Represent Equations
- Use number line diagrams to represent and write addition and subtraction equations.
- Let’s write equations and represent them on a number line.
