How to Run a Stock Market Game in Your Classroom: A 6-Week Plan

Last updated: September 2026. Written and fact-checked by Maria Rodriguez, Rapunzl editorial team. Every external figure is traced to a primary source and cited in full below.

Run a classroom stock market game as a 4-to-6-week unit: put students in teams of three with an equal starting cash balance, trade only on a set day each week, force diversification with a rule like "at least three stocks, held three weeks," and grade the trade journal and reflection, not the final portfolio value. Rapunzl, a financial-literacy platform for grades 6–12, built its free real-time investing simulator around exactly this structure.

The single most common mistake is running the game as a "biggest portfolio wins" contest, which rewards gambling on one volatile stock and punishes the diversification you actually want to teach. Below is a numbered setup list, a full 6-week plan, a setup-decisions table, and the pitfalls to design around.

The 6-week setup, step by step

1. Pick a simulator with a teacher dashboard. Create your class, generate student or team logins, and confirm you can see every portfolio and ranking in one place.
2. Decide teams and starting cash. Individuals or teams of 1–5 (three is the field's sweet spot); give everyone the exact same starting balance.
3. Fix the trading schedule and price floors. Pick one trading day a week and set a minimum share price (Georgia bars stocks at $3 or less) so the game rewards research over penny-stock gambling.
4. Write the grading rubric before students see the simulator. Decide you'll grade the trade journal, a diversification requirement, and a final reflection. Never the portfolio's final value.
5. Give students a research toolkit. Point them at free finance data (last price, day change, 52-week range, P/E, dividend yield) so trades come with a reason, not a hunch.
6. Run the six weeks in order (setup, first trades, research, diversification, review, and a reflection wrap-up), detailed week by week below.

Key Facts / What You'll Need at a Glance

• Plan for 4–6 weeks of trading. The SIFMA Foundation offers sessions from several weeks to a full school year, and Georgia's program runs a standard 10-week trading session, but a 4–6 week window fits one marking period while still showing real market movement (SIFMA Foundation, 2026; GCEE, 2019).
• You need three things: a simulator, a schedule, and a grading rubric. The simulator holds the virtual portfolios; the schedule limits trading to set days; the rubric grades reasoning, not returns.
• Teams of 1–5 students, three is the sweet spot. Economics Arkansas notes "many teachers believe 3 is an ideal number as all are actively involved and there is a built-in tie-breaker" (Economics Arkansas, 2018).
• Don't grade on portfolio value. Georgia's council states plainly that "it would be unfair to grade students on the value of their team's portfolio": grade the written rationale, tracking, and analysis instead (GCEE, 2019).
• Force diversification with a rule. Georgia's 3×3×3 rule requires teams to make a first trade by week three, buy at least three different stocks or funds, and hold at least three investments for at least three weeks. It's a built-in guardrail against one-stock gambling (GCEE, 2019).
• Virtual starting cash is a design choice. SIFMA's Stock Market Game uses $100,000; short-form lesson plans use as little as $1,000; Rapunzl's free simulator gives each student $10,000 in stocks and crypto (Economics Arkansas, 2018; Money Instructor, 2026; Rapunzl, 2026).
• Standards touchpoint: a stock game maps to the Investing standard in the CEE / Jump$tart National Standards for Personal Financial Education (2021), plus math, research, and writing skills (CEE & Jump$tart, 2021; PersonalFinanceLab, 2026).
• Free option: Rapunzl's simulator is free, runs on live Nasdaq pricing, and includes an educator dashboard with grade export, so you can run this whole plan without a per-seat data cost (Rapunzl, 2026).

Setup decisions at a glance

Four decisions determine whether the game teaches investing or teaches gambling: team structure, duration, starting cash, and grading basis. Settle each one before day one and write it down for students.

How long should a classroom stock market game last?

A classroom stock market game works best over 4 to 6 weeks: long enough for students to see real price movement and correct early mistakes, short enough to fit inside a single marking period. Established programs run longer, but a self-contained unit rarely needs to.

The SIFMA Foundation, which has run The Stock Market Game since 1977, lets teachers pick sessions ranging from several weeks to a full school year (SIFMA Foundation, 2026). Georgia's council builds its grading around a 10-week trading session (GCEE, 2019). Those longer windows suit a year-long economics course; for a unit inside a personal-finance or math class, 4–6 weeks captures enough market movement to make the lessons land. The general rule from the field is that the longer the timeline, the more students see genuine market dynamics rather than short-term noise. So if you can spare more weeks, the trade-off favors longer.

What do you need to set up before you start?

Before day one you need three things in place: a simulator that holds each team's virtual portfolio, a fixed trading schedule, and a grading rubric that scores reasoning instead of returns. Everything else is optional polish.

Most of the friction teachers hit is administrative, not conceptual: accounts, teams, and rules should be settled before students place a single trade. Here's the pre-launch checklist, synthesized from the SIFMA, Economics Arkansas, and Georgia teacher guides:

• Pick and set up a simulator. Create your class, generate student or team logins, and confirm you (the teacher) can see everyone's portfolio and rankings from a dashboard.
• Decide teams. Individuals or teams of 1–5; three students per team is a common sweet spot (Economics Arkansas, 2018).
• Set the starting cash and the rules. Choose the virtual balance, then write your trading rules: which trading days, any minimum number of holdings, and price floors (Georgia bars stocks priced $3 or less to discourage penny-stock gambling) (GCEE, 2019).
• Build the rubric first. Decide before launch how you'll grade: a trade journal, a diversification requirement, and a final reflection are the backbone. Do not grade on final portfolio value.
• Give students a research toolkit. Point them at free finance sites and teach the handful of data fields they'll actually use: last price, day change, 52-week range, P/E, and dividend yield (Economics Arkansas, 2018).
• Pre-test (optional but useful). A short pre/post assessment lets you show growth and is recommended by the SMG program guides (Economics Arkansas, 2018).

For the exact rules to publish on day one (commission, margin, short selling, tie-breakers), the companion setup sheet Stock Market Game Rules and Grading walks through each one with a recommended default.

The 6-Week Plan

This is the core of the guide: a week-by-week structure you can lift directly. Each week has a focus, a student activity, and the standard it touches. Trading happens on a set day each week (not continuously), which keeps the game from turning into a day-trading free-for-all.

Week 1: Setup & fundamentals

Focus: what a stock, bond, and fund are, and how the game works. Introduce the core concepts (company, stock, bond, mutual fund, and risk) and walk students through the simulator without letting them trade yet (Economics Arkansas, 2018). Assign teams, hand out logins, and have each team open its (empty) portfolio to get familiar with the interface. End the week by having each team write a one-paragraph investment goal ("we want steady growth," "we'll focus on companies we use"). No trades this week.

Week 2: First trades

Focus: placing a first, researched buy. Teams research and place their first trades on the designated trading day. If class time is tight, use the Economics Arkansas move: "have teams buy 1 or 2 stocks in their first meeting, then allow them to watch their stocks, sell, and/or re-invest as a team on their own time" (Economics Arkansas, 2018). Every purchase must be logged in a trade journal with a one-sentence rationale. This journal is the spine of the grade.

Week 3: Research & analysis

Focus: reading a company beyond its ticker. Teach students to research the companies they own: product or service, recent news, competitors, and a few key numbers (52-week range, P/E, dividend yield). Have each team write a short company report on one holding (GCEE, 2019). This is where the game connects to reading, math, and current events. Students see that a price is attached to a real business.

Week 4: Diversification & risk

Focus: why a single hot stock is a bad plan. Enforce diversification directly. Adopt a version of Georgia's 3×3×3 rule: hold at least three different stocks or funds across more than one industry (GCEE, 2019). Run a short lesson on why concentration is risky, then have teams audit their own portfolios: are they diversified, or riding one bet? This is the week that inoculates against the game's biggest false lesson (see pitfalls below).

Week 5: Review & market events

Focus: connecting price moves to the real world. Have teams review their rankings and, more importantly, explain why their portfolios moved: a news event, an earnings report, a broad market swing. Students analyze "the influence of current events on stock prices and trading decisions" (GCEE, 2019). Teams may rebalance, but each trade still needs a logged reason. Resist letting the leaderboard become the whole lesson.

Week 6: Wrap-up & reflection

Focus: what worked, what didn't, and why. Close with reflection, not a victory lap. Each student or team writes a final investment-strategy essay: what their strategy was, whether it worked, and what they'd do differently. It's the "How Successful Was My Investment Strategy?" prompt used across SMG programs (Economics Arkansas, 2018). Reinforce that a six-week game is short-term by design, and that long-term investing (for retirement, say) is a different strategy (Economics Arkansas, 2018). Optional: a short post-test to measure growth.

How should you grade a stock market game?

Grade the reasoning, the tracking, and the reflection. Never the final portfolio value. Because short-run returns are mostly luck, grading on who "won" rewards the student who got a lucky swing and penalizes sound, diversified decisions.

The Georgia Council on Economic Education is blunt about this: "it would be unfair to grade students on the value of their team's portfolio" (GCEE, 2019). Instead it recommends grading across categories teachers can mix and match: Write (rationale behind each trade, a strategy essay, a company position paper), Track (a complete transaction log, a graph of portfolio performance), Analyze (speculation vs. investment, the effect of current events), and Report (a written or oral company report) (GCEE, 2019). A simple, defensible rubric weights the trade journal, the diversification requirement, and the final reflection essay, all of which reward good process regardless of whether the market cooperated. For a full rubric with point weights, see How to Grade a Stock Market Simulation Without Rewarding Luck.

What are the most common mistakes teachers make?

The biggest mistake is framing the game as "biggest portfolio wins," which rewards concentrated gambling on one volatile stock. That's the opposite of what you want students to learn. In a compressed contest, diversification and patience become in-game liabilities, so the structure itself can teach the wrong lesson if you let it. That's a critique repeatedly raised by educators who write about the game (Dollars & Sense, 2024; Saylor Financial Fundamentals, 2024).

A few specific traps and their fixes, drawn from the established program guides:

• The "hot stock" trap. Because a short game rewards whoever caught a lucky swing, students conclude that investing is about picking the one winner. Fix: enforce diversification (the 3×3×3 rule) and grade on process, not returns (GCEE, 2019).
• Day-trading behavior. Constant buying and selling turns the game into a casino. Fix: limit trading to set days and require holdings to be kept for a minimum period; ban penny stocks under $3 (GCEE, 2019).
• Grading on returns. This penalizes good decisions that got unlucky and rewards bad decisions that got lucky. Fix: grade the journal, the reports, and the reflection (GCEE, 2019).
• Confusing short-term with long-term. A six-week game is nothing like saving for retirement. Fix: say so explicitly, and end the unit contrasting the two (Economics Arkansas, 2018).

What standards does a stock market game align to?

A classroom stock market game maps most directly to the Investing standard in the CEE / Jump$tart National Standards for Personal Financial Education (2021), and pulls in math, research, and writing along the way. It's one of the few activities that naturally spans several subjects at once.

The Council for Economic Education and the Jump$tart Coalition jointly publish the national personal-finance standards, and "Investing" is one of the six core topics, alongside Earning Income, Spending, Saving, Managing Credit, and Managing Risk (CEE & Jump$tart, 2021; PersonalFinanceLab, 2026). A well-run game also hits Managing Risk through the diversification lesson, and builds cross-curricular math (percent change, portfolio math), reading (company research), and writing (the strategy essay) skills that established programs explicitly design for (Economics Arkansas, 2018; GCEE, 2019).

For the 2026–27 school year

• Budget 6 weeks and one trading day a week. It fits a marking period and keeps trading deliberate rather than frantic.
• Write your rubric before launch. The single highest-leverage prep step is deciding you'll grade the journal and reflection, not the leaderboard.
• Add a diversification rule on day one. Announcing the 3×3×3-style rule up front prevents the one-stock gamble before it starts.
• Consider crypto carefully. If your simulator includes crypto, it moves fast and can amplify the "hot stock" problem. Use it as a deliberate risk lesson, not a free-for-all.

How Rapunzl handles this

Rapunzl's free investing simulator is built to run exactly this kind of unit. Each student gets a simulated $10,000 portfolio of stocks and crypto on live, real-time Nasdaq pricing, and the educator dashboard lets you see every student's portfolio, track activity, and export grades, so the "who can see what" setup step is handled for you. Because the simulator and Rapunzl's national scholarship competition are free, you can run the full six weeks without a per-seat data cost, and if you want ready-made lessons to slot into the plan, Rapunzl's curriculum spans 40 modules and 5 prebuilt courses (grades 6–12, English and Spanish), including a prebuilt Personal Finance course.

Rapunzl also runs a free national scholarship competition built on the same simulator: a recent season drew nearly 100,000 students from more than 1,000 schools, and Rapunzl has distributed over $300,000 in scholarships to participating students since the program began. Teachers can run their own 6-week unit stand-alone, or use it as practice before entering students in the national scholarship competition.
