About Stock Market Sim

Stock Market Sim places students on the trading floor of a global financial intelligence center, where each position shows a buy price and a current price. Working out the percentage gain or loss builds the percentage-change and financial-reasoning skills of Grades 7 and 8, framed as real investment decisions on a professional dashboard.

Chosen by the skills this activity practises.

A hand for grown-ups

Before you start
A handful of real coins is the best possible resource here. Sort them together before you start.
While they work
Let them make the same amount in different ways — 20p as two 10s, or 10 + 5 + 5. Flexibility is the goal.
Afterwards
Give them a small real purchase to work out — "this is 30p, what change from 50?". Real stakes focus the mind.
Watch out for
Assuming a bigger coin is worth more (that a big 10p beats a small 20p). Handling real coins and their values fixes this.
Away from the screen
Play shop with real coins. Let them handle small real transactions and work out the change.

How to play

  1. A question appears on screen

    A maths question is shown in large text at the centre of the play area. A timer bar begins counting down from 120 seconds.

  2. Choose the correct answer

    Answer options are shown as large buttons. Tap or click the correct option. Any input method works — touch, mouse or keyboard.

  3. Build your streak

    Each consecutive correct answer increases your streak. A longer streak lights up the flame icon and adds a bonus multiplier to the XP you earn for the level.

  4. Finish the level

    Each level has 4 questions. Complete them to earn the full level reward (+10 XP, plus up to +10 XP for a perfect run). Progress is saved locally and shown on the Parent Dashboard.
