Garage Construction Costs: Guided Practice for Grade 9
By Philip G.
A guided-practice packet in which 9th graders read a detached garage's project specifications and price list, then work through multi-step calculations for plates, studs, headers, and sheathing. Students build measurement, unit-conversion, and cost-estimation skills while showing every step of their work.

Teacher Guide & Tips
- Use this as a 45 to 60 minute small-group or pair activity after students have practiced unit rates and perimeter/area calculations, and have students read the specifications aloud together before starting any math.
- Discussion question: Why do builders round up to whole boards and whole sheets, and what would happen to a budget if they rounded down?
- Scaffold for struggling readers: Have them first sketch the garage's four walls and label each length, then compute perimeter before tackling the plate and stud questions.
- Extension for advanced students: Ask them to compare the cost of buying 16-foot boards versus 10-foot studs for the plates and studs and explain which option saves more money.
- Estimated time: about 50 minutes, with extra time if students need to check each calculation against the price list.
