Exit Ticket: Cost Estimation
1. Hook & Introduction (10 mins)
Welcome students as "Apprentice Architects." Explain that every great building starts with a budget and a blueprint.
"Architects, today we need to calculate the cost of our foundation materials. If we don't estimate correctly, our building might collapse before we finish!"
2. Guided Instruction (20 mins)
Step A:
Rounding for Estimation: Use slide 4 to practice rounding material costs (e.g., $432 for lumber rounds to $430 or $400). Discuss why we estimate before doing exact math.
Step B:
Two-Step Problems: Model a problem: "We have $900. Concrete costs $345 and steel costs $289. How much money will be left?" Demonstrate rounding first, then exact calculation with regrouping.
3. Independent Practice (20 mins)
Distribute the Construction Costs Worksheet . Circulate and support students using the "Addition/Subtraction Tool" (regrouping boxes) on the worksheet.
4. Wrap-up & Exit Ticket (10 mins)
Architectural Review: Have students share one strategy they used to subtract across zeros. Collect the Exit Ticket .
