(20 – 25 minutes)
Student-Centered Learning Option
7.10B and 7.11A SOLVING TWO-STEP EQUATIONS
- Allow time for students to read the Tell Me More… section on page 78 and the stepped-out examples on pages 79-81.
- Have students try the You Try It! problem on page 79.
- As needed, support student reasoning and productive struggle through questioning (see below).
- Bring students back together as a whole group to debrief the content and examples.
Explicit Instruction Option
7.10B and 7.11A SOLVING TWO-STEP EQUATIONS
- Read the Tell Me More… section on page 78.
- Work through each example. If necessary, use the provided steps.
- Guide students to try the corresponding You Try It! problem on page 79.
Instructional Hints
- Emphasize the connections between a concrete model (cups and counters), pictorial model (strip diagram), and properties of operations that justify the steps taken to solve an equation.
- The additive inverse allows you to add the opposite of a number to generate 0. Adding 0 to any side of the equation does not change its value.
- The multiplicative inverse allows you to divide any number by itself and get 1. Multiplying by 1 on any side of the equation does not change its value.
Questioning Strategies
- Clarifying Question(s)
- What does the problem ask?
- Can you explain that in a different way?
- Focusing Question(s)
- What is this problem about?
- Advancing Question(s) [ask and walk away]
- What would you need to add to or subtract from both sides of the equation to make the addend 0?
- What would you need to multiply or divide both sides of the equation by to make the coefficient 1?
- Assessing Question(s)
- How do you know your answer is correct?
Assessment Strategies
Formative Assessment
- Assign the Practice questions to students. Use student responses to gauge their proficiency with the content.
- Use the Additional Questions as needed.
