Lesson Objective

Students will solve two-step equations using multiple operations.

• Which operation do we do first when solving?
• Why do we undo operations in reverse order?
• How do we check a two-step solution?
• Where do we see two-step equations in real life?

Two-step equation, order of operations, inverse operations, sequence

CCSS.MATH.7.EE.B.4

Description: Students learn that some equations require two steps to solve. Using visual step-by-step guides, they practice identifying the operations in an equation and undoing them in reverse order (PEMDAS backwards). Purpose: To develop systematic problem-solving skills and reinforce the concept of inverse operations. DOK Level: 2-3 (Application and Strategic Thinking)

• Step-by-step visual cards: Provide color-coded steps for solving
• For struggling learners: Use only addition/subtraction + multiplication/division by 2 or 3
• For advanced learners: Include equations with fractions or decimals
• Anchor chart: Display "Steps to Solve" visually in the classroom

• Observation: Do students follow steps in order?

• Guided practice worksheet: 6 two-step equations with visual supports

• Partner work: Solve together and explain each step

 

• Exit ticket: Solve one equation and show all steps

 

• Two-step equation cards (color-coded by operation)

• Step-by-step solution guides with visuals

• Anchor chart for solving steps

• Practice worksheets with visual supports
