Step by step
The question
Question: draw a bar chart of Mon 5, Tue 3 and Wed 7.
How many in all?
Mon 5, Tue 3, Wed 7
1 Draw the axes
The names go along the bottom.
The numbers go up the side.
The side counts in 1s, starting at 0.
Careful!
The side always starts at 0.
Then the bars compare fairly.
Careful: the side starts at 0
2 Draw the bars
Mon: 5.
Its bar goes up to 5 on the side.
Tue: 3.
Wed: 7.
All the bars have the same width, with gaps between them.
3 Read the chart
In all: we add the bars.
5 plus 3 plus 7 is 15.
= 5 + 3 + 7 = 15
4 Check
Let's check in two parts: the first two make 8, the rest make 7.
8 plus 7 is 15.
So it is right!
8 + 7 = 15
Let's look back.
First: draw the axes.
Then: draw the bars.
Then: read the chart.
Last: check.
Answer
= 5 + 3 + 7 = 15
