Asking the right questions invites critical thinking about the "big ideas" (enduring understanding) in mathematics. Try these questions during your lesson.

**1. What do you need to know? What do you need to find out?**Students are invited to pinpoint the problem and the information needed for its solution.**2. How can you choose a strategy that will help you solve the problem?**Students peruse their strategies to match the needs of the problem.**3. Which strategy did you choose? Why?**Students justify their choice of strategy by describing how it addresses the conditions of the problem.**4. What will you do first to solve the problem?**What will you do next? Students make sense of how step works toward finding the solution.**5. How did you solve the problem?**Students define the steps they chose to solve the problem.**6. How will you check your answer for reasonableness?**Checking strategies may include using inverse operations or estimation.**7. How do you know the answer makes sense?**Students justify their answers using common sense, logical reasoning, or estimation strategies.
