The three big ideas

Data is the information you collect — like everyone's favourite fruit in your class.
Tally marks are a quick way to count: draw four upright lines, then a fifth line crossing them to make a bundle of 5.
Counting in bundles of five makes a big total easy to add up at the end.

Worked example. A pictograph uses 🍎 = 5 apples. One row has 4 apple pictures. How many apples is that?

Each picture stands for 5, so 4 × 5 = 20 apples.

A pictograph shows data using repeated small pictures or symbols.
A key tells you how much one picture is worth, e.g. one book = 10 books.
To read it, count the pictures in a row and multiply by the key value.

Common mix-up: always check the key first. If one picture means 5, then 3 pictures are 15, not 3 — forgetting the key gives the wrong total.

A bar graph shows data as bars. The taller the bar, the bigger the number.
The side scale tells you what each step on the bar is worth, so you can read the amount.
Bar graphs make it easy to compare: the tallest bar is the most popular, the shortest is the least.

Data pictures around you

A class survey

Ask your classmates their favourite fruit, count with tally marks, then draw a bar graph. In one glance everyone can see which fruit won — that is the power of a picture.

Weather & attendance charts

Schools track sunny and rainy days, or daily attendance, on simple charts. A taller bar or more pictures instantly shows which day or month had the most.

Comparing scores

Sports-day points for each house, or runs scored in a match, shown as bars make it easy to see who is ahead — no need to read a long list of numbers.
