Year 3 Maths — Bar graphs with scales
Read values off a bar graph whose scale counts in steps of more than one, and choose a sensible scale of your own.
Name: ________________________
1.This bar graph shows how many people visited a library on four days. Tap the bar for the day with the fewest visitors.
Write the number of the part.
2.Why does a bar graph need a scale written up the side?
- a) So the height of a bar can be turned into a number
- b) To make the graph look neat
- c) To give the bars their names
- d) To show which bar is the tallest
3.A bar graph's scale counts in tens. A bar reaches exactly halfway between 30 and 40. What number does it show?
4.A bar graph's scale counts in fives. Match each bar to the number it shows.
- 2 lines up
- 3 lines up
- 5 lines up
- 8 lines up
- 12 lines up
- 10
- 15
- 25
- 60
- 40
5.A graph has ten lines above zero and the largest number to show is 45. Which scale fits best?
- a) 5 for each line
- b) 1 for each line
- c) 20 for each line
- d) 2 for each line
6.A bar graph's scale counts in threes. A bar shows 21. How many lines tall is it?
7.A bar graph has four bars, showing 60, 45, 30 and 25. What is the difference between the tallest bar and the shortest?
8.A bar graph's scale counts in fives. Sort each value by whether its bar lands exactly on a marked line.
