Budgeting and Consumer Math

Warm-up

Quick brainstorm: What do students spend money on? Make a list (snacks, games, books, etc.).

Explore

Students create a personal budget based on a given monthly income (real or hypothetical). They list expenses and calculate what's left. Then, they solve consumer math problems: applying discounts, calculating tax, comparing prices.

Formalize

Record the key formulas:

Budget: Income − Expenses = Savings. Discount: Sale price = Original price × (1 − discount%). Tax: Final price = Price × (1 + tax%). Unit price: Price ÷ Quantity.

Emphasize: A balanced budget means living within your means. Saving requires choosing to spend less than you earn.

Practice

Students complete a budget, solve discount and tax problems, and compare unit prices. Exit ticket: one budget or consumer math question.
