Year level: 6

Strand: Statistics

Lesson length: 50–60 mins

In this lesson, students engage with megalitres in a real-world context by exploring dam water storage capacities across Australia.

They interpret and compare real-world data sets and analyse graphs in terms of their range and shape.

This lesson is the third of 5 lessons that connect the cross-curriculum priority of Sustainability with Number, Measurement and Statistics. It can also complement the science content description AC9S6U04.

### Achievement standard

Students compare distributions of discrete and continuous numerical and ordinal categorical data sets as part of their statistical investigations, using digital tools.

### Content descriptions

Students interpret and compare data sets for ordinal and nominal categorical, discrete and continuous numerical variables using comparative displays or visualisations and digital tools; compare distributions in terms of mode, range and shape. AC9M6ST01

List one thing that you:

• found interesting or surprising in today’s lesson
• are wondering about from today’s lesson.

Prerequisite student knowledge

• Familiarity with units of measure for capacity
• Interpret numbers beyond a million
• Familiarity with line graphs

Language

• litres, kilolitre, megalitre
• water storage levels
• capacity
• line graph
• range
• shape of graph

Some students may:

• have difficulty working with numbers beyond 1 million
• find it challenging to identify and interpret real-world data.

## What you need:

• Lesson plan (Word)

• Teacher’s slides (PowerPoint)

• 10 cm × 10 cm × 10 cm MAB cube and an empty 1 litre container, for example, a milk carton

• At least 1 device per group of 2–3 students with access to BOM Australia water storage dashboard
