Teacher's field guide

What Students Need to Do: Students use income and expense information to create a workable budget in a spreadsheet. They use formulas to total amounts, find the remaining balance, and revise spending when conditions change.
What Mastery Looks Like: Students create a clear spreadsheet that correctly calculates total income, total expenses, and money remaining. They adjust spending when income or costs change and explain the tradeoffs they made.
Common Misconceptions: Students often budget with gross pay instead of take-home pay or mix weekly, monthly, and yearly amounts. They may forget irregular costs, double-count expenses, or type totals instead of using spreadsheet formulas.
How to Assess It: Give students a monthly take-home income of $2,400 and six expenses. Ask them to build a spreadsheet budget, calculate the balance, and revise it after a $150 rent increase.

Lesson moves

Give pairs income and expense cards to sort, total, and enter into a spreadsheet without exceeding the monthly income.
Ask students to write which expense they would reduce after losing $200 in monthly income and explain why.
Run a budget challenge where teams draw surprise expense cards and revise spreadsheet categories while keeping a nonnegative balance.
Use local rent, food, transportation, and utility prices to build a realistic first-apartment budget for an entry-level salary.
