Likelihood of Events

Active learning helps students grasp probability because abstract terms like likely and unlikely become concrete when applied to real scenarios. Fifth class students refine their thinking through hands-on experiences that reveal how chance operates in everyday life.

Activity 01

• Human Barometer
• 30 min · Small Groups

Sorting Activity: Probability Cards

Prepare cards with 20 everyday events, like 'snow in July' or 'heads on a coin flip'. In small groups, students sort cards into five categories using probability terms and justify placements. Groups share one example per category with the class.

Differentiate between an 'unlikely' event and an 'impossible' event.

Facilitation Tip

During the Sorting Activity, circulate to listen for students who pair impossible with unlikely and redirect with a quick question about the marble bag results.

What to look for

Provide students with three scenarios: 1. Rolling a 7 on a standard six-sided die. 2. Drawing a blue marble from a bag containing only red marbles. 3. It raining tomorrow in a desert. Ask students to write the correct probability term (impossible, unlikely, even chance, likely, certain) for each scenario and one sentence explaining their choice for scenario 1.

• 25 min · Pairs

Simulation Game: Spinner Predictions

Create spinners divided into unequal sections labeled with colors. Pairs predict likelihood of landing on each color using terms, then spin 20 times and tally results. Discuss if predictions matched outcomes.

Predict the likelihood of various everyday events occurring.

Facilitation Tip

For Spinner Predictions, ask students to explain why their chosen probability card matches the spinner’s outcome before they record results.

What to look for

Pose the question: 'Is it more likely or unlikely that you will eat an apple today or that you will see a dog today?' Allow students to discuss their reasoning in pairs, encouraging them to use the vocabulary terms and justify their predictions based on their experiences.

Whole Class: Event Voting

List 10 school events on the board, such as 'bell rings at 3pm'. Students vote secretly with terms on whiteboards, then reveal and debate justifications as a class. Tally votes to show class consensus.

Justify the use of specific probability terms for different scenarios.

Facilitation Tip

While holding Event Voting, pause after each vote to ask a student to restate the group’s reasoning using the correct term.

What to look for

Hold up cards with simple events written on them, such as 'Flipping a coin and getting tails', 'The moon being made of cheese', 'Getting a score of 100% on a test you did not study for'. Ask students to show fingers representing the likelihood: 1 finger for impossible, 2 for unlikely, 3 for even chance, 4 for likely, 5 for certain.

Activity 04

• Human Barometer
• 20 min · Individual

Individual: Prediction Journal

Students list five personal events, assign probability terms, and predict outcomes for the week. At week's end, they reflect individually on accuracy and revise terms if needed.

Differentiate between an 'unlikely' event and an 'impossible' event.

What to look for

Provide students with three scenarios: 1. Rolling a 7 on a standard six-sided die. 2. Drawing a blue marble from a bag containing only red marbles. 3. It raining tomorrow in a desert. Ask students to write the correct probability term (impossible, unlikely, even chance, likely, certain) for each scenario and one sentence explaining their choice for scenario 1.

A few notes on teaching this unit

Teach likelihood through repeated exposure to the same vocabulary in varied contexts so terms become sticky. Avoid rushing to definitions; instead, let students discover distinctions through trials and peer talk. Research shows children solidify understanding when they explain their reasoning to others.

By the end of the activities, students will confidently use vocabulary to describe events and justify choices with evidence from trials or discussions. Their language will shift from vague notions to precise, measurable terms.

Watch Out for These Misconceptions

• During Sorting Activity: Probability Cards, watch for students who group unlikely and impossible together.

  Bring their attention to the marble bag trials and ask them to predict how often an unlikely event (like drawing a blue marble from a mostly red bag) would occur compared to an impossible one.

• During Spinner Predictions, watch for students who label an even chance spinner as likely.

  Have them flip a coin 20 times and tally heads and tails to see that equal results match the even chance term, not a higher probability.

• During Event Voting, watch for students who debate whether a certain event like sunrise is truly fixed.

  Prompt them to recall the class vote results and ask what evidence from daily life supports that certainty.
