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)

Decide the method with a quick question: "Is a variable already alone?" → substitution. "Do coefficients match or are opposites?" → elimination. Always check the final pair in both equations.

Graph simple systems on grid paper to see the crossing point.

y = x and x + y = 6.
Answer: x = 3, y = 3.
x + y = 5, x − y = 1. Add.
Answer: 2x = 6 → (3, 2).
y = 2 and x + y = 7.
Answer: (5, 2).

🚀 Stretch it (got everything right)

Solve: 2x + 3y = 7 and 3x − 4y = 2.
Answer: Multiply the first by 4 and the second by 3: 8x + 12y = 28 and 9x − 12y = 6. Add: 17x = 34, so x = 2 and y = 1.
Create a real-world system with solution (6, 10) and explain what each variable means.
Answer: Example: a + c = 16 tickets; 8a + 5c = 98 dollars → 6 adults, 10 children.
