Free maths practice app

Chance and probability practice app

A quick classroom-ready app for chance words, possible outcomes, likely outcomes from counter bags, expected frequencies and simulation results.

Chance words

Students choose impossible, unlikely, likely or certain for everyday probability scenarios.

Possible outcomes

Spinner questions ask students to identify every colour that could be landed on.

Counter bags

Bag questions help students decide which colour is more likely from the counts shown.

Experiments

Expected frequency and simulation questions connect chance to repeated trials.

What students practise

The app is built for short, focused chance practice where students need to connect a situation, visual model or trial result with probability language.

  • choosing impossible, unlikely, likely or certain
  • identifying possible outcomes on a spinner
  • deciding which counter colour is more likely from a bag
  • estimating expected frequencies from equal spinner sections
  • using simulation results to estimate probability

How it fits a lesson

Use it after modelling chance language, during rotations, as a warm-up, or as follow-up practice when students need more examples of probability ideas.

  • start with chance words when students are still building the language
  • move to outcomes when students need to list what can happen
  • use bag questions to compare likelihood from visible counts
  • use experiments when students are ready to connect probability with repeated trials

Why it helps

Chance questions can be tricky because students often rely on everyday guesses instead of checking the possible outcomes, counts or trial results.

  • connects probability language with concrete examples
  • uses spinners, counter bags and simulation results
  • supports repeated practice without creating a worksheet pile

Frequently Asked Questions

Is the chance and probability app free?

Yes. Students, teachers and families can open the chance and probability practice app in a browser for free.

What chance tasks are included?

The app includes chance words, possible outcomes, likely outcomes from bags, expected frequencies and chance simulations.

Does the app include visual models?

Yes. Students see spinner, counter bag and simulation displays, depending on the question type.

Does it replace teaching probability?

No. It is designed for practice after students have seen how to use chance language, outcomes, counts and trial results.
