- 45 minutes
- Grades 9–12
- Beginner
- Activity: small groups

- Explain why budgets are reviewed and revised
Materials
- Slide deck and a projector
- Worksheet (one per student)
- Budget Calculator (projected, or on student devices)
- Exit ticket slips (bottom of the worksheet)
45-minute agenda
- 0–5 min
Warm-up
Post: “If you had $1,000 a month to live on, what are the first five things you'd have to pay for?”
- 5–12 min
Direct instruction
Present the lesson slides. Make sure students leave with these points:
- A budget is a plan made before you spend.
- Always budget from take-home pay.
- 50/30/20 (needs/wants/savings) is a starting guideline — adjust it to your life.
- Review monthly. Adjusting the plan is part of the plan.
Use the “See it” slide (The 50/30/20 guideline on $2,000 of take-home pay) to make the idea visual.
- 12–17 min
Worked example
Walk through “Aaliyah's first real budget” on the slides. Pause before the result and ask students to predict it.
- 17–22 min
Live demo
Project build a monthly budget from the slides or the Budget Calculator. Change one input at a time and have students call out what they think will happen.
- 22–34 min
Budget a Life
Format: small groups · 12 minutes
- Give each group a take-home pay card: $1,800, $2,400, or $3,000 a month.
- Groups split it with 50/30/20, then list specific expenses in each part (rent share, groceries, phone, transportation, fun, savings).
- Draw a change card for each group: rent rises $100, hours are cut by $200 a month, or a $50 streaming bundle is added.
- Groups revise the budget without touching savings first, then share what they cut.
What to look for: Starting splits: $1,800 → $900 / $540 / $360; $2,400 → $1,200 / $720 / $480; $3,000 → $1,500 / $900 / $600. Good revisions trim wants before savings.
- 34–39 min
Check for understanding
Use the question slides — or run them as a Four Corners game. Answers:
- Using the 50/30/20 guideline, about how much goes to savings and debt payoff? — D. $360
- What's the most useful next step? — A. Look at why it happened, then adjust next month's plan or cut somewhere else.
- You should build your budget from your gross pay (before taxes), since that's what you earned. — False
- 39–42 min
Discussion
- Why do so many people stop budgeting after a month or two? How could you make it easier to stick with?
- How might the 50/30/20 split look different for a high school student living at home versus a recent graduate paying rent?
- 42–45 min
Exit ticket
Prompt: Why do you budget from take-home pay instead of gross pay?
Answer: Take-home pay is what actually reaches your account after taxes and deductions. Budgeting from gross pay plans to spend money you never receive.
Differentiation
Common misconception
“A budget means I can't have any fun.” A budget plans for wants on purpose so you can enjoy them without stress.
Support
Provide a budget template with categories already listed and the 50/30/20 amounts pre-calculated.
Extension
Build a zero-based budget (every dollar assigned) for the same income and compare it with the 50/30/20 version.
