Charts and Pictograms
In Year 3, children learn to read and make sense of bar charts, pictograms and tables, the three main ways numbers are shown as pictures. They find a single value by reading it off the chart, and they get to grips with a pictogram key, where one symbol can stand for two or more things. It is the first real taste of handling data, and none of it is as daunting as it sounds.

Good to know
Reading charts
Here are the same numbers shown three ways: a table, a bar chart and a pictogram. Find a value in one, then spot it in the others.
Pictogram
Each picture = 2
- Apple
- Pear
- Plum
- Lime
Table
| Fruit | How many |
|---|---|
| Apple | 6 |
| Pear | 3 |
| Plum | 5 |
| Lime | 4 |
| All together | 18 |
For grown-ups
Reading a chart is only half the skill; the other half is using it to answer something. Year 3 introduces one and two-step problems such as how many more and how many altogether, where a child reads off two values and then either finds the difference or adds them together. Learning that "how many more" means subtract, while "altogether" means add, builds the careful, question-led thinking that data handling relies on right through school, and into the graphs and statistics of secondary maths.

- How many more, and how many altogether
How to help at home
The whole skill is reading a value off the picture, so make the picture talk before you talk about numbers.
- Read charts you already own. The telly guide, a sticker album, a tally of who wants which pizza: ask "which has the most?" and "how many more footballs than stickers?" so the maths lands on something real.
- On a bar chart, get them to slide a finger from the top of the bar straight across to the number line and read the value off the side scale, rather than guessing from the height.
- On a pictogram, always check the key first: "one picture means 2". Then count in twos, and remember a half picture is 1, not a half.
- For "how many more" or "how many fewer", steer them to subtract: find both amounts, then take the smaller from the bigger. "How many altogether" means add the two amounts instead.
Where children get stuck
The commonest pictogram slip is counting pictures instead of reading the key. If one symbol stands for 2, a row of four symbols is 8, not 4. Children who race ahead count the symbols as ones and land on half the real total. Fix it by saying the key out loud every single time before counting, then counting in twos along the row: 2, 4, 6, 8. A half symbol then clearly means 1, because it is half of 2.
The other sticking point is "how many more" and "how many fewer". Many children add the two amounts when the question wants the gap between them, or they read one bar and stop. Both "more" and "fewer" are asking for the difference, so the move is the same: find both values, then subtract the smaller from the bigger. It helps to say "the difference between 8 and 5 is 3" so the word and the subtraction become one idea.
