## Description of activity

Students are given the results of a school survey and asked to interpret the information and represent it in different ways.

1. Students are given the results of a school survey.
2. They write the missing features, such as labels, on the graph.
3. Students explain the information presented in the graph, including how many students were surveyed.
4. They represent the information in different ways.

The suggested time allocation for this activity is 45 minutes.

## Suggested materials

Worksheet, rulers, pencils

## Prior learning

Students have had experience reading and interpreting different forms of data representation. They have constructed and labelled a variety of graphs to represent information. Students have discussed how a scale is used and have constructed and answered questions based on the observations and analysis of information provided in graph form.

## Outcomes

Data (DS3.1)
Displays and interprets data in graphs with scales of many-to-one correspondence
Applying Strategies (WMS3.2)
Selects and applies appropriate problem-solving strategies, including technological applications, in undertaking investigations
Reasoning (WMS3.4)
Gives a valid reason for supporting one possible solution over another

## Criteria for assessing learning

Students will be assessed on their ability to:

• interpret a graph and provide missing features
• display data in different ways
• explain information presented graphically
