Learning goals
- Apply inverse operations (addition/subtraction, then multiplication/division) to isolate a variable
- Construct two-step linear equations of the form px + q = r from practical verbal scenarios
- Fluently verify solutions by substituting the derived value back into original algebraic expressions
Before you begin
Use inverse operations and interpret equality as a balance.

Teaching and response guide
- Model the target skill: apply inverse operations (addition/subtraction, then multiplication/division) to isolate a variable. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Use inverse operations and interpret equality as a balance.
- Discuss an incorrect response using this distinction: Undo operations in the correct order and make the same change on both sides.
Watch for: Undo operations in the correct order and make the same change on both sides.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
