Bar charts worksheet: Answers and working

1. 1
Look at two neighbouring numbers up the side. How far apart are they?
Neighbouring numbers are 1 apart, so a square stands for 1.
2. 8
Find the 🍪 bar and read across from its top to the number on the side.
The top of the 🍪 bar is level with 8.
3. 11
See what one square stands for. The 🍓 bar stops halfway between two lines: what does half a square stand for?
A square stands for 2, so half a square stands for 1. The 🍓 bar is 5 squares and a half: 10 + 1 = 11.
4. 10
Read off how many 🍪 and how many 🍓 there are, then subtract.
🍪 is 20 and 🍓 is 10: 20 − 10 = 10.
5. 65
See what one square stands for, read off each of the four bars, then add them up.
Add up the four bars: 65.
6. 7
On the 🍌 row each full gate is 5. Count the full gates first.
Each full gate is 5; count on the strokes left over: 7.
7. 15
A full gate is 5 strokes. Count in fives, 3 times.
Each gate is 5; counting in fives 3 times: there are 15 🐰.
8. 7, 17, 11
On each row count the full gates in fives, then add the strokes left over.
Five for each full gate, plus the strokes left over: 7, 17, 11.
9. 4
A square is 2. 9 is odd: find the even number just below it and how many squares that is. What part of a square is the 1 left over?
4 squares stand for 8, 1 short; 1 is half of 2, so add half a square: 4 and a half.
10. 20
Count how many each row records first, then add the three rows.
Add the three rows: 5 + 6 + 9 = 20.

11. B. 🐶
Compare the heights of the four bars: the tallest one is the most.
The tallest bar is the most: 🐶.
12. B. 2
The 10 squares must reach 18. Try each choice: does 10 times it reach 18?
10 squares must reach 18: the smallest of 1, 2, 5 and 10 that does is 2.

Marking: 2 for the working, 1 for the answer, 1 for the sentence.

13. 60 children
Each child chose just one, so the four amounts add up to the children. Read each bar first.
Each child chose one, so the four bars add up to the number of children: 60.
14. 25 children
Find the tallest and the shortest bars, read off their amounts and subtract.
Tallest bar minus shortest bar: 25.
15. 13 children
Read off how many chose 🐰 and how many chose 🍌, then add.
7 + 6 = 13.
16. 4 squares
Squares = amount ÷ what a square stands for. How many 5s make 20?
Squares = amount ÷ what a square stands for: 20 ÷ 5 = 4.
17. 7 vehicles
Count the 🚗 row and the 🚌 row: each full gate is 5.
There are 19 🚗 and 12 🚌: 19 − 12 = 7.
18. 30 people
Work out how many squares apart the two bars are, then remember each square is 5 people.
8 − 2 squares apart, 5 people each: 30.
