Unit 10 · Lesson 1
Some people think math is just a school subject with little relevance outside the classroom. But math is everywhere — chefs use it all day in restaurant kitchens, gardeners use it in planter beds, and it is hiding in jobs and hobbies all around you. A chef scales a recipe up for forty covers and works out how much stock to order. A gardener measures a planter bed and calculates the soil needed to fill it. Today you will name the math hiding inside jobs like these, and you will do some of it yourself — area, volume, rates, and estimates that have to be close enough to act on.

Turn & Talk — Launch
The chef plans a planter that is 4 feet long and 2 feet wide, filled 1 foot deep with soil. What two different things does the chef calculate about that planter, and why are they different?
👂 Listen For
A strong answer names area (4 × 2 = 8 square feet, a flat surface) and volume (4 × 2 × 1 = 8 cubic feet, a filled space) and explains why one is squared and one is cubed. A weak answer just says 'they use math' without naming either calculation.
Extend: If the same planter needed soil 2 feet deep instead of 1 foot, would the area change, the volume change, or both? Justify your answer.

Listen for students distinguishing a flat, 2D measurement (area, plants fitting on top) from a 3D measurement that fills space (volume, soil filling the box) — not just guessing based on the word 'planter.'
Extend: A chef's inventory task and a gardener's soil task both involve counting or measuring amounts. Are they the same kind of math? Defend your answer.

Turning off the water while brushing saves 4 gallons per brushing, twice a day, for 365 days — a total of 2,920 gallons a year. How is this the same kind of math as the chef ordering ingredients?
👂 Listen For
A strong answer names the same structure — multiplying a per-event amount by how many times it happens — and correctly gets 2,920 gallons. A weak answer just says 'both use numbers.'
Extend: A household of 3 people each saves 2,920 gallons a year. Generalize a rule for finding the savings for any number of people, and use it to find the savings for 7 people.

🎯 Listen For · Common Errors
• A strong answer names area (4 × 2 = 8 square feet, a flat surface) and volume (4 × 2 × 1 = 8 cubic feet, a filled space) and explains why one is squared and one is cubed. A weak answer just says 'they use math' without naming either calculation.

• A strong answer names the same structure — multiplying a per-event amount by how many times it happens — and correctly gets 2,920 gallons. A weak answer just says 'both use numbers.'
• Listen for students naming a specific strategy tied to scaling a daily rate to a yearly total — not just "I multiplied." They should connect the strategy to the numbers in the problem.
Common mistake: Believing math only 'counts' when it happens in a classroom — and walking past the calculating, measuring, and projecting inside jobs, hobbies, and chores every day.
Answer Key (Teacher Appendix)
Hide this slide during presentation or move to the end of your copy.
✓ Practice 1: 2,920 gallons — 8 gallons a day × 365 days = 2,920 gallons in a year.
✓ Practice 2: 8,760 gallons — 2,920 gallons per person × 3 people = 8,760 gallons a year.
✓ Practice 3: 2,920 gallons — 5 people save 5 × 2,920 = 14,600 gallons and 4 people save 4 × 2,920 = 11,680 gallons. The difference is 14,600 − 11,680 = 2,920 gallons — exactly one more person's savings.
✓ Practice 4: 4 plants — 8 square feet ÷ 2 square feet per plant = 4 plants.
✓ Exit ticket: People use math every day in their professions and hobbies, and it solves problems around the house too — The summary makes the claim in three parts: professions use math, hobbies use math, and it is a good tool for problems around your house.
