## Lesson details

### Key learning points

1. Data can be collected to help solve a problem involving length.
2. When we collect data, we need to decide which units to measure in: mm, cm or m.
3. Representing data as a bar graph can help us interpret the data.

### Common misconception

Drawing tables and graphs from scratch can be tricky for some children.

Provide scaffolds of tables and graphs where necessary.

### Keywords

• Data - Data is a collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

• Interpret - When we interpret anything, including data, we explain its meaning.

Complete this lesson practically where possible encouraging 'point in time' measurements so that the data can be considered discrete. Cross-curricula links to science and using the data handling cycle in science.
