The question

Question: draw a bar chart of red 5, blue 8, green 3 and yellow 6.

Which is the most?

red 5, blue 8, green 3, yellow 6

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

Red: 5.

Its bar goes up to 5 on the side.

Blue: 8.

Green: 3.

All the bars have the same width, with gaps between them.

3 Read the chart

The tallest bar is blue.

Across to the side: it reaches 8.

So the most is blue, with 8.

= most: blue (8)

4 Check

Let's check with the numbers: 8 is bigger than all the others.

So it is right!

8 > 5, 3, 6

Let's look back.

First: draw the axes.

Then: draw the bars.

Then: read the chart.

Last: check.

Answer
= most: blue (8)
