🌟 Overview
AC9M3P02 focuses on conducting chance experiments, identifying possible outcomes, and recording results. Students learn how to list all outcomes of simple experiments and use methods such as tally charts and frequency tables to record data from repeated trials.qcaa.qld.edu+1
Students explore variation by comparing results across different trials and groups. This helps them understand that chance experiments can produce different results each time, even when the conditions stay the same.

🔍 Key vocabulary
🎲 Chance experiment — an activity where the result is uncertain…
🎯 Outcome — a possible result of a chance experiment
❓ Possible — something that can happen
🔄 Trial — one attempt or repetition of a chance experiment
✏️ Tally mark — a mark used to record one result
🔢 Frequency — the number of times a particular outcome occurs
📋 Frequency table — a table that shows how often each outcome happened

Related Learning Areas
- ✏️ AC9M3P01 — Describing Chance and Likelihood
- This related content focuses on using language such as “likely,” “unlikely,” “certain,” and “impossible” to describe the chance of events. Students build understanding of probability before conducting experiments.mathematicshub.edu+1
- ✏️ AC9M3ST01 — Collecting and Recording Data
- Students apply data collection skills from statistics to record the results of chance experiments. Tally charts and frequency tables from this code are used directly in chance investigations.
- ✏️ AC9M3ST02 — Representing and Interpreting Data
- After recording experiment results, students represent data using column graphs, pictograms, and tables. This code helps students visualise and interpret variation in their chance experiment data.
- ✏️ AC9M2P01 — Year 2 Chance Learning
- Year 2 chance learning provides an important foundation. Students build on earlier experiences of describing everyday events using chance language before conducting more structured experiments in Year 3.
📝 Helpful Tips
- Use real materials like dice, coins, and spinners to make experiments concrete and engaging.
- Before each experiment, ask students to predict all possible outcomes and record them in a list.
- Model how to record one trial with one tally mark in the correct row of the frequency table.
- Teach students to group tally marks in fives: |||| with the fifth mark crossing the group.
- Keep the number of trials manageable (e.g., 20–30 rolls) so students can focus on accuracy and recording.
- After recording, have students compare their results with a partner to see variation.
- Ask: “Did everyone get the same results? Why or why not?” to introduce the concept of variation.
- Use the same experiment across the class and create a combined class frequency table to show larger-scale variation.
- Connect to real-life examples: weather forecasts, sports results, or game outcomes all show variation.
