Retirement Accounts: 401(k)s and IRAs

Retirement accounts require students to grasp abstract financial concepts like compound growth and tax advantages, which are best taught through active learning. By simulating real decisions, analyzing employer matches, and comparing account types, students see the immediate impact of their choices rather than memorizing rules.

Activity 01

• Simulation Game
• 30 min · Pairs

Simulation Game: The Power of Starting Early

Students calculate the final retirement balance for two investors: Alex contributes $3,000/year from age 22-32 (10 years) then stops, and Jordan starts at 32 and contributes $3,000/year until 65 (33 years). Using a 7% annual return calculator, students compare final balances and write a one-paragraph explanation of what drives the difference.

Differentiate between a 401(k) and an IRA.

Facilitation Tip

During the Simulation: The Power of Starting Early, circulate to ensure pairs calculate totals correctly and discuss how compound growth changes with different start times.

What to look for

Present students with two hypothetical scenarios: one detailing a 401(k) with a 50% employer match up to 6% of salary, and another describing an IRA with specific contribution limits. Ask students to identify which account offers immediate 'free money' and explain why.

Activity 02

• Case Study Analysis
• 25 min · Individual

Case Study Analysis: Employer Match , Free Money Analysis

Present a scenario: an employee earns $45,000 and their employer offers a 50% match on contributions up to 6% of salary. Students calculate how much the employee must contribute, how much the employer adds, and the total annual contribution. Then calculate the 20-year cost of declining the match entirely. The 'walking away from free money' framing is consistently motivating.

Explain the benefits of employer-matching contributions.

Facilitation Tip

For the Case Study: Employer Match, Free Money Analysis, provide a calculator or spreadsheet so students can experiment with different match rates and salary percentages.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you have $100 to save for retirement. If your employer offers a 401(k) with a 100% match on the first $50 you contribute, how would you allocate that $100 between a 401(k) and an IRA to maximize your initial growth, and why?'

Activity 03

• Think-Pair-Share

Think-Pair-Share: Traditional vs. Roth , Which Is Better?

Present two scenarios: a person who expects to be in a higher tax bracket in retirement than now, and a person who expects to be in a lower bracket. Students determine which account type benefits each scenario, share with a partner, then discuss why the answer depends on predicting future tax rates , and why that uncertainty matters for diversification across both account types.

Analyze the tax advantages of different retirement savings vehicles.

Facilitation Tip

In the Think-Pair-Share: Traditional vs. Roth, Which Is Better?, assign roles to ensure both students contribute before sharing with the class.

What to look for

Ask students to write down the primary difference between a traditional and a Roth retirement account, and then list one specific benefit of an employer match that an individual IRA cannot provide.

Gallery Walk: Contribution Limits and Rules

Post four stations covering 401(k) contribution limits, IRA contribution limits, Roth IRA income eligibility limits, and required minimum distributions. Students record the current rules at each station and identify one scenario where each rule would affect a real financial decision. Use current IRS figures for accuracy.

A few notes on teaching this unit

Teachers should frame retirement accounts as tools for future security rather than distant abstractions. Use real-world numbers and employer scenarios to make the topic tangible. Avoid overwhelming students with tax code details; instead, focus on how the accounts work and why they matter. Research shows students retain financial concepts better when they apply them to personal scenarios rather than abstract rules.

Students will confidently explain how employer matches work, compare traditional and Roth accounts using concrete numbers, and justify why starting early matters. They will also accurately interpret contribution limits and rules for both account types.

Watch Out for These Misconceptions

• During Simulation: The Power of Starting Early, watch for students who believe the person who contributes more total money over time will always end up with a larger balance.

  Use the simulation’s final balances to redirect students: highlight how the early starter ends with more despite contributing less total money, and ask them to trace the compound growth in the spreadsheet.

• During Case Study: Employer Match, Free Money Analysis, watch for students who undervalue the employer match and treat it as optional rather than immediate income.

  Have students calculate the match as part of their take-home pay in the case study, then ask them to compare the total compensation with and without the match.

• During Think-Pair-Share: Traditional vs. Roth, Which Is Better?, watch for students who assume Roth accounts are always superior regardless of income or tax rate.

  Guide the discussion using the provided tax bracket scenarios in the activity handout, asking students to calculate the tax impact for each type under both current and retirement income levels.
