Classroom Market Fair

The Trading Game

A checkout system that turns a school market day into a real business lesson. Students run their own stalls, iPads become their cash registers, and every sale is tracked live. When the market closes, the app works out who made the most profit — after deducting costs, salaries and rent, and paying tax.

How It Works

From setup to the final results in four steps.

1

Set Up

The teacher logs in as admin, names the 12 groups (two classes of six), and enters each group's product or service and its material costs.

2

Run the Market

Students log in on iPads as their group and ring up each sale on a big, touch-friendly number pad — mistakes can be deleted on the spot. Meanwhile a staff Investment Manager runs the Stock Exchange, recording customer investments in their favourite teams.

3

Watch It Live

A projector shows the public dashboard — a live leaderboard for each class that refreshes every couple of seconds as sales and investments come in. No login needed.

4

Reveal the Results

The teacher closes trading and the app does the accounting: it deducts material costs, salaries and rent, applies tax (20% by default, adjustable — and never on a loss), then crowns the group with the highest final profit.

The Business Lesson

The app does the maths — the students learn what it means.

Sales + Investments Costs Salaries Rent = Profit
Profit Tax = Final Profit

The team that sells the most doesn't always win. Students discover that revenue is not profit: materials, wages and rent all eat into the takings, and the tax office takes a share of whatever is left — but never of a loss. That's what running a real business feels like.

Who Does What

Three roles keep the market running.

Teacher / Admin

Sets up the groups and costs, manages logins, opens and closes trading, and reveals the final results.

Student Checkout

Each group runs its own stall and uses an iPad as a cash register to record every sale.

Investment Manager

Staffs the Stock Exchange, where customers can invest in a team to boost its revenue.
