Coach: look at the exit check results and the paper practice. Go back over every item a student missed: read it together, have the student explain their thinking, then show the correct thinking. Use the reteach routine below for anyone who missed two or more. Students who got everything right take the stretch task.

🔄 Reteach it (missed two or more)

Use the method chooser chart: no x-term → square roots; easy factors → factor; a = 1 and b even → complete the square; otherwise → formula.

Always check by substituting each solution into the original equation. Circle any solution that doesn't make sense in context.

If ab = 0, then...
Answer: a = 0 or b = 0.
Discriminant formula?
Answer: b² - 4ac.
Discriminant = 0 means ___ solution.
Answer: one.

🚀 Stretch it (got everything right)

Write a quadratic equation with exactly one real solution and explain how you know.
Answer: Any perfect-square trinomial = 0.
Explain when you would choose factoring over the quadratic formula.
Answer: When the quadratic factors easily with integers.
