Possible Directions:

First two pages:

1. Copy enough for all students (not back-to-back)

2. Go through the example as a whole class, having students fill out the notes page as you go.

3. With the two practice problems, you can complete it as a whole class or give time to try the two problems independently or with partners.

4. Have students cut both pages out and glue them into their notebooks.

Extra Practice Sheet:

Can be assigned for homework or in-class practice, or given as an

Cut along the dotted lines and glue it into your notebook.

Learning Target: I can use inverse operations to solve a two-step equation

Review: Solve each one-step equation. Show your work.

1) n - 8 = -3

2) -2m = -24
