You are the lead organizer for your neighborhood block party. Use number sense to plan the goodie bags, the schedule, and the budget — without wasting a single dollar.
The neighborhood council gave your team a $300 budget and a list of jobs. Work through four phases. Each phase uses real number sense — greatest common factor, least common multiple, decimal operations, and multi-digit division. Fill in every box, hit Calculate or Check, and finish the planning checklist and reflection at the end. Then print your plan for the council.
You have donated supplies and want to make the largest number of identical goodie bags with no leftovers. The number of bags is the GCF of your two supply counts.
List the factors of each number, or use prime factorization. The GCF is the biggest factor they share. Example: GCF(48, 36) = 12, so you can make 12 bags, each with 48÷12 = 4 stickers and 36÷12 = 3 bars.
The DJ plays a hype song every few minutes and the bubble machine fires on its own cycle. When do they line up again at the same moment? That is the LCM.
List the multiples of each number until you find the first one they share. Multiples of 6: 6, 12, 18, 24… Multiples of 8: 8, 16, 24… They meet at 24 minutes.
Add up your shopping cart with decimal addition, then see how much of the $300 budget is left. Stay in the green!
Line up the decimal points and add. Then subtract the total from 300.00. If your total is over 300, trim a category!
You spent money — now split shared costs fairly. Divide the total cost by the number of guests to find the cost per person, then check your answer.
Write a short pitch (3–5 sentences) that uses your numbers from above. Convince the council your plan is smart and fair.
| Category | 4 — Expert | 3 — Proficient | 2 — Developing |
|---|---|---|---|
| Factors & Multiples (GCF/LCM) | GCF and LCM both correct with reasoning shown | Both answers correct | One answer correct or partial reasoning |
| Decimal Operations | Budget is accurate to the penny and under $300 | Budget total is accurate | Minor decimal/place-value errors |
| Division | Cost per guest correct and division check correct | Cost per guest correct | Attempted with a computation error |
| Communication | Pitch clearly justifies every number used | Pitch uses most numbers | Pitch is unclear or missing numbers |
