- This related content focuses on representing data in different ways, such as tables, graphs and other displays. Students use the data they have collected to identify patterns, compare results and answer questions.
- 🔎 AC9M3ST03 — Conducting Statistical Investigations
- Students conduct guided investigations by asking questions, collecting data, representing results and interpreting what the data shows. This code connects strongly with classroom surveys and research activities.
- 🌱 AC9M2ST01 — Year 2 Data Learning
- Year 2 data learning provides an important foundation. Students build on earlier experiences of sorting, counting and representing information before working with more organised data sets in Year 3.
📝 Helpful Tips
- Model thinking aloud when interpreting graphs: “I can see that… This tells me…”
- Teach students to identify the question before looking at the graph
- Use sentence starters for conclusions: “The data shows…”, “This tells us…”, “We can see that…”
- Encourage students to check their answers by re-reading the graph
- Start with simple comparisons (most/least) before moving to difference questions
