Lesson

Remember when we used a number line to order whole numbers ? Let's practice.

Plot the following numbers on the number lines:

a

Plot 3 on the number line below.

Worked Solution

b

Plot 528 on the number line below.

Worked Solution

c

Plot 700 on the number line below.

Worked Solution

Idea summary

To plot a number on a number line we must consider how many units each space between ticks represents.

When we divide 1 unit into 10 equal pieces, it is broken into 10 tenths, as shown below.

This video looks at how to plot and read tenths on a number line.

Plot 0.3 on the number line.

Worked Solution

Idea summary

When we divide 1 unit into 10 equal pieces, it is broken into 10 tenths.

When we divide 1 unit into 100 equal pieces we end up with hundredths. We can also get the size of 1 hundredth by dividing 1 tenth up into 10 equal pieces, as shown below.

This video looks at how to plot and read hundredths off a number line.

What number is shown on the following number line?

Worked Solution

Idea summary

10 hundredths make 1 tenth. The larger the number, the further to the right it will be on a number line.
