What students learn in AC9M5ST02
This unit helps students build a clear, usable understanding of Interpret line graphs representing change over time; discuss the relationships.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: interpret line graphs representing change over time; discuss the relationships that are represented and conclusions that can be made.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- reading and interpreting different line graphs, discussing how the horizontal axis represents measures of time such as days of the week or times of the day, and the vertical axis represents numerical quantities or ordinal categorical variables such as percentages, money, measurements or ratings such as fire hazard ratings interpreting real-life data represented as a line graph showing how measurements change over a period of time and make simple inferences
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: interpret line graphs representing change over time; discuss the relationships that are represented and conclusions that can be made
- E1: reading and interpreting different line graphs, discussing how the horizontal axis represents measures of time such as days of the week or times of the day, and the vertical axis represents numerical quantities or ordinal categorical variables such as percentages, money, measurements or ratings such as fire hazard ratings
- E2: interpreting real-life data represented as a line graph showing how measurements change over a period of time and make simple inferences
- E3: matching unlabelled line graphs to the context they represent based on the stories of the different contexts
- E4: interpreting the data represented in a line graph making inferences; for example, reading line graphs that show the varying temperatures or UV rates over a period of a day and discussing when would be the best time to hold an outdoor assembly
- E5: exploring how line graphs can be used to train AI systems to make predictions by providing historical data and showing trends
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- Rushing to a rule before checking the concrete model, drawing or number sentence.
- Using the correct answer once but not being able to explain why it works.
- Mixing up similar vocabulary such as more/less, before/after, longer/shorter or equal groups/sharing.
