Design it. Spin it. Test it. Discover probability!
Can your students design a spinner where one colour is most likely to appear, another is least likely, and two colours have an equal chance?
Spinner Challenge is an engaging, hands-on mathematics investigation that gets students designing, constructing and testing their own probability spinners.
Using paper, coloured pencils and split pins, students create working spinners, predict outcomes, conduct chance experiments and compare their results.
But there's a challenge! Students must design spinners that meet specific probability conditions, explain their mathematical thinking and investigate why experimental results don't always match predictions.
This isn't just another probability worksheet! Students learn through creating, experimenting, problem-solving and discovering mathematical concepts for themselves.
Build Your Spinner: Design and construct a working spinner that meets specific probability conditions.
Predict and Investigate: Explore likely, unlikely, certain and impossible outcomes.
Spin and Record: Conduct chance experiments and record results using tally marks.
Compare and Explain: Investigate variation between predicted and actual outcomes.
Extension Challenges: Create increasingly complex spinner designs.
Spinner Templates: Nine ready-to-use spinner templates with different numbers of equal sections.
Probability and chance
Likely, unlikely, certain and impossible events
Comparing and ordering the likelihood of outcomes
Probability scales and percentages
Conducting chance experiments
Recording and interpreting results
Mathematical reasoning and justification
✓ Genuinely hands-on and engaging
✓ Minimal preparation and inexpensive materials
✓ Open-ended challenges with multiple possible solutions
✓ Encourages mathematical discussion and reasoning
✓ Opportunities for differentiation and extension
✓ Perfect for independent, partner or small-group investigations
✓ Reusable spinner templates for future probability activities
Perfect for: Probability units, maths investigations, hands-on learning, enrichment activities and problem-solving lessons.
Recommended for: Years 3–6
Format: Instant-download, 4-page A4 printable PDF.
