Charts and graphs · Year 6
In Year 6 you learn: pie charts.
Charts turn a table of numbers into a picture you can read at a glance. Bar charts compare separate groups. Pie charts show how a whole is shared out. Line graphs show how something changes over time.
Key facts
- Line graph: plot a point for each time and join them; steeper means faster change.
- Check the scale: an axis that does not start at 0 can make small differences look big.
