# Handling Data: Comparing distributions

Comparing distributions lesson plan

## KS3 Bitesize

### Objectives

• Pupils interpret graphs and diagrams, including pie charts

• AT4 Level 5

### Resources

• Worksheet
• Pencils
• Teacher designed homework sheet

### Teaching activities

#### Mental Starter

• Simple addition and subtraction questions will help with the stacked bar graph later. Also fractions of amounts will help with the pie chart. E.g. "½ of 20, 1/6 of 24, 48 ¸6 etc. 40 - 10, 90-30, etc."

#### Activity

1. The teacher could start the group off by looking at the three diagrams and asking...

"What type of diagram is this?"

"What fraction is this?" (on the pie chart)

2. Pupils could then be set off on the worksheet
3. The teacher should bring the class together at the end to discuss the answers. Pupils in the class should be asked to provide the answers

#### Extension

• The next worksheet provides a natural extension

#### Plenary

• Pupils discuss how they got the answers to the questions
• The teacher may ask, "What extra information did we need for the pie chart and percentage stacked bar chart? Why?"

#### Homework

• The teacher could design a similar sheet where this time the tables are given and pupils have to draw the diagrams
