## Lesson details

### Key learning points

1. A key on a pictogram and the scale of a bar chart can provide key information about the data shown.
2. Annotating pictograms and bar charts helps to solve problems.
3. Rearrange equations to make it easier to calculate missing numbers.

### Common misconception

Pupils may find it tricky using scales to read bar charts, especially when the scale uses multiples of five.

Encourage pupils to think about where intermediate numbers are on bar charts (e.g. numbers from 10 to 15). They may count from one number to another or make marks to show approximately where numbers would be found.

### Keywords

• Bar chart - A bar chart uses rectangular bars to show different values.

• Pictogram - A pictogram uses pictures to show information.

• Table - A table has information arranged in rows and columns.
