🍕 6TH-8TH GRADE PIZZA GAME: Rational Pizza — Run Your Own PIZZA Shop!
Overview
Students work in teams as pizza shop owners. They must buy ingredients, price pizzas, sell to customers, keep books, and track profits/losses. Every round (one “day”), students face math challenges involving fractions, decimals, percentages, ratios, and integers.
🎲 Materials Needed
Pizza boards: Paper circles (laminated or cardboard) divided into slices (fractions: 1/2, 1/4, 1/8, 1/12)
Ingredient cards: cheese, sauce, toppings, crusts, specials (with prices)
Menu boards: students design their own menus with fractions/decimals/percents for prices
Order cards: “customers” request specific pizzas (e.g., “3/4 veggie + 1/4 pepperoni”)
Ledger sheets: bookkeeping records for income, expenses, tips, losses, taxes
🧮 Math Standards Covered
Ratios & Proportions: scaling recipes, adjusting ingredient costs
Fractions & Decimals: combining pizza slices, converting between fractions/decimals
Percents: tax, tips, discounts, profit margins
Integers: bookkeeping (negative = losses, refunds, spoiled food)
Operations with Rational Numbers: addition, subtraction, multiplication, division across decimals, fractions, and integers
Problem Solving: optimization (e.g., how to maximize profit with limited toppings)
⚙️ How to Play
Step 1: Set Up Shops
Students form teams of 2–4.
Each team gets:
$100 startup money
A ledger
Ingredient cards (with costs)
A blank menu sheet
Step 2: Buy Ingredients
Teams purchase ingredients at wholesale cost (e.g., $3 for a cheese pizza base, $0.75 per topping, $0.50 per extra slice).
They must track expenses (subtract from startup cash).
Step 3: Design Menu
Teams set pizza prices using rational numbers:
Example: A 12-slice pizza costs $12. If sold by the slice: $1.50 each.
Offer discounts (percents) for whole pizzas, or markups (percents) for premium toppings.
Step 4: Customer Orders
The teacher (or other teams) plays customers drawing Order Cards.
Example Orders:
“Buy 3/4 of a veggie pizza. Apply a 10% student discount.”
“Buy 2 pepperoni slices at $1.75 each. Add 8.5% sales tax.”
“Return a burnt pizza. Subtract $8 from your income.”
Step 5: Math Challenge (Gameplay Round)
For each order, teams must:
Assemble the pizza with fractions (visual manipulatives).
Do the math:
Add fractions (pizza slices ordered).
Convert fractions ↔ decimals ↔ percents.
Apply tax, tips, or discounts.
Record income & expenses in ledger.
Step 6: Profit & Loss
At the end of each “day” (round), teams:
Calculate profit/loss = (Sales – Expenses).
Record in ledger using positive & negative integers.
Option: Introduce unexpected event cards (spoilage, free pizza day, price surge).
🏆 Winning the Game
After 5 rounds (5 days), the team with the highest profit (or least loss) wins.
Students present their bookkeeping to show rational number fluency.
🔢 Example Order Card
Customer Card:
“I want 3 slices of cheese pizza. Each slice costs $1.25. Add 8% sales tax. Leave a 15% tip.”
Math Challenge:
Subtotal = 3 × $1.25 = $3.75
Tax = $3.75 × 0.08 = $0.30
Tip = $3.75 × 0.15 = $0.56
Total = $3.75 + $0.30 + $0.56 = $4.61
Students record $4.61 income in ledger.
🎉 Extensions
Middle School Challenge:
Introduce supply & demand pricing.
Add negative integers for losses (rent, spoiled food).
Offer loans with interest (percent application).
STEM Tie-in: calculate nutritional facts (ratios, decimals).
ELA Integration: Write an advertisement or jingle for their pizza shop.
