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. Questions:
- Using the 50/30/20 guideline, about how much goes to savings and debt payoff?
- What's the most useful next step?
- You should build your budget from your gross pay (before taxes), since that's what you earned.
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?
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.
