Pictograms and bar charts
First see what one grid line stands for.
How to do it
Method
First see what one grid line stands for
Each line 5, 6th line: 6 × 5 = 30
Another way
Read, then work it out
9 − 4 = 5
In full
First see what each grid line stands for: in a pictogram each picture is 1, so count them; on a bar chart, see which line the top of the bar reaches, then read the number at the side. Each line 5, the bar reaching the 6th line: 6 × 5 = 30. To compare two, take one from the other: Apple 9 people, Banana 4, 9 − 4 = 5, so Apple has 5 more; for both together, add. Or read each item's number first, then work it out — the same answer.
Worked examples
Have a go first, then open each one for the answer and the working.
Example 1
Cycle: ? people
Show the answer and working
Answer: Cycle: 6 people
Each picture stands for 1. Count them: Cycle has 6 pictures, so 6
Example 2
Melon has ? more than Orange
Show the answer and working
Answer: Melon has 5 more than Orange
Each picture stands for 1: Melon has 9 pictures, Orange has 4 pictures, 9 − 4 = 5
Example 3
Run has ? more than Swim
Show the answer and working
Answer: Run has 5 more than Swim
Each picture stands for 1: Run has 7 pictures, Swim has 2 pictures, 7 − 2 = 5
Example 4
4A and 4C: ? cans in all
Show the answer and working
Answer: 4A and 4C: 90 cans in all
4A: each grid line stands for 10, the bar reaches line 1, 1 × 10 = 10; 4C: each grid line stands for 10, the bar reaches line 8, 8 × 10 = 80; 10 + 80 = 90
