The Language of ChanceActivities & Teaching Strategies
Active learning helps Year 3 students grasp chance vocabulary because it turns abstract ideas into tangible experiences. When students physically interact with spinners, coins, and real-world scenarios, they anchor probabilistic language in memory and build confidence using terms like impossible and likely.
Learning Objectives
- 1Classify everyday events as impossible, unlikely, likely, or certain using precise mathematical vocabulary.
- 2Compare the likelihood of two different events occurring, justifying the comparison with mathematical reasoning.
- 3Explain how prior results from chance experiments can inform predictions, and identify when such predictions might be misleading.
- 4Justify the use of a probability scale from impossible to certain for describing outcomes in games and nature.

Stations Rotation: Probability Spinners
Prepare spinners divided into impossible, unlikely, likely, certain sections. Groups spin 20 times, tally outcomes, and classify each spinner's results using vocabulary cards. Discuss as a class why predictions shift with more trials.
Prepare & details
Differentiate between an event being 'unlikely' and 'impossible'.
Facilitation Tip: For Probability Spinners, pre-cut spinners with uneven sections so students immediately see how design affects outcomes.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Pairs Prediction: Coin Toss Challenge
Pairs predict outcomes for 10 coin tosses using terms like likely or unlikely, then test and record actual results. Partners compare predictions to data and adjust language for future tosses. Share one insight with the class.
Prepare & details
Predict how we can use previous results to predict future outcomes, and when this is misleading.
Facilitation Tip: During Coin Toss Challenge, have pairs record five tosses quickly to prevent overthinking and encourage spontaneous language use.
Setup: Groups at tables with matrix worksheets
Materials: Decision matrix template, Option description cards, Criteria weighting guide, Presentation template
Whole Class: Nature Probability Hunt
List local events like 'it will rain today' or 'a bird will fly overhead.' Class votes using probability scale, tracks outcomes over a week via chart. Review tallies to discuss prediction accuracy.
Prepare & details
Justify why we use a scale from impossible to certain to describe the world.
Facilitation Tip: In Nature Probability Hunt, assign small teams specific weeks to observe and record daily weather, building patience and reliability in observations.
Setup: Groups at tables with matrix worksheets
Materials: Decision matrix template, Option description cards, Criteria weighting guide, Presentation template
Individual: Sorting Scenario Cards
Provide cards with events like 'sun rising tomorrow.' Students sort into impossible to certain, justify in journals, then pair share to refine. Collect for formative feedback.
Prepare & details
Differentiate between an event being 'unlikely' and 'impossible'.
Facilitation Tip: Set up Sorting Scenario Cards on tables with labeled baskets for impossible, unlikely, likely, and certain to make peer discussions visual and efficient.

Teaching This Topic
Approach this topic through repeated, short trials so students experience chance as dynamic, not static. Avoid rushing to definitions; instead, let students debate and adjust their language as they test outcomes. Research shows that young learners benefit from concrete experiences before abstract labeling, so prioritize hands-on exploration over worksheets in initial lessons.
What to Expect
Successful learning looks like students using precise chance vocabulary confidently in discussions and tasks. They should justify their choices with evidence from trials, such as noting that unlikely outcomes still occur or that certain events repeat reliably over time.
These activities are a starting point. A full mission is the experience.

- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring Sorting Scenario Cards, watch for students who label events as impossible simply because they are rare.
What to Teach Instead
Prompt students to test their claim by physically using the spinners or flipping coins 20 times, then revising their labels based on actual results.
Common MisconceptionDuring Coin Toss Challenge, students may claim a streak of heads increases the chance of tails on the next flip.
What to Teach Instead
Have pairs repeat the 10-flip sequence three times and compare streaks to show outcomes are independent of past results.
Common MisconceptionDuring Nature Probability Hunt, students might expect the sun to rise at exactly the same time every day.
What to Teach Instead
Guide students to track sunrise times for a week and discuss how certain events occur reliably but not at fixed moments.
Assessment Ideas
After Sorting Scenario Cards, collect worksheets and note which students use precise terms correctly and which need reinforcement.
During Coin Toss Challenge, listen for students explaining whether past results influence the next flip, assessing their grasp of independent events.
After Probability Spinners, collect labeled spinner drawings and check that each section is correctly categorized with justifications.
Extensions & Scaffolding
- Challenge students who finish early to design a spinner with two impossible outcomes and explain why these cannot occur.
- For students who struggle, provide scenario cards with pictures instead of text to support vocabulary recall.
- Deeper exploration: Have students create a class booklet of daily chance observations, including predictions and outcomes for a month.
Key Vocabulary
| Impossible | An event that cannot happen. For example, a standard six-sided die landing on a 7. |
| Unlikely | An event that has a low chance of happening. For example, flipping a coin and getting heads three times in a row. |
| Likely | An event that has a high chance of happening. For example, the sun rising tomorrow. |
| Certain | An event that is guaranteed to happen. For example, a standard six-sided die landing on a number less than 7. |
| Outcome | A possible result of a chance event, such as rolling a 3 on a die or flipping a coin and getting tails. |
Suggested Methodologies
Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
