Step by step
The question
Question: draw a bar chart of June 45, July 60, Aug 35 and Sept 50.
How many more July than Aug?
1 Draw the axes
The names go along the bottom.
The numbers go up the side.
The biggest number is 60.
So the side counts in 10s, starting at 0.
Each line on the side is 10 more.
2 Draw the bars
June: 45.
Its bar goes up to 45 on the side.
45 is between 40 and 50.
July: 60.
Aug: 35.
35 is between 30 and 40.
All the bars have the same width, with gaps between them.
3 Read the chart
Careful!
The side counts in 10s.
So read the number on the side, not how many squares.
July reaches 60.
Aug reaches 35.
How many more: we take away.
60 minus 35.
60 minus 35 is 25.
So there are 25 more July than Aug.
4 Check
Let's check: 35 plus 25 is 60.
So it is right!
Let's look back.
First: draw the axes.
Then: draw the bars.
Then: read the chart.
Last: check.
