A 20-problem Halloween decimal worksheet built around a monster café menu, with operations, estimation, unit pricing, and budgeting.
Menu mathematics gives decimal operations a reason to be precise. Students estimate bills, compare prices, calculate change, scale orders, and work within a budget instead of completing disconnected rows of decimal arithmetic.
Have students write trailing zeros when aligning money amounts. If calculators are used, require an estimate and written setup before checking the arithmetic.
Use the monster menu prices in each question. Estimate first, then calculate the exact amount and label money answers correctly.
All prompts below are included in the printable version. Keep the answer key closed until the activity is complete.
Read and compare decimal prices: Bat Bites $3.75, Mummy Wrap $6.40, Witch's Brew $2.85, Ghost Pie $4.95, Spider Sundae $5.60.
Add and subtract money amounts accurately.
Multiply decimal prices by whole-number quantities.
Divide costs and make decisions under a constraint.
Use multi-step decimal reasoning and test reasonableness.
Open-ended and experimental responses may differ when the reasoning meets the stated conditions.
