🌟 Overview
Compare and Interpret Graphs develops Year 3 students’ higher-order thinking skills with data. Students learn how to compare categories within bar graphs, interpret what the data shows, and draw simple conclusions.
Students use bar graphs to answer questions involving addition, subtraction and comparison. This helps them understand that graphs are not just for showing information, but for making sense of data and solving problems.

Related Learning Areas
- ✅ AC9M3ST01 — Collecting and Recording Data
- Students collect and record categorical data using tally charts, frequency tables and spreadsheets. This data can then be represented as bar graphs and interpreted, connecting strongly with data collection skills.
- ✅ 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 where students interpret their own collected data.
- ✅ AC9M2ST02 — Year 2 Interpreting Data
- Year 2 interpreting skills provide an important foundation. Students build on earlier experiences of reading simple picture graphs and column graphs before working with more complex comparisons and conclusions 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
