Here is a line with nothing on it but a 0 at one end and a 1 at the other. There are no other marks yet.
Where would you put 0.5 on this line? Point in the air with your finger before anyone says a word.
Here is a number line from 0 to 1, marked every 0.1. Each time a decimal goes on it, watch where its marker lands and think about why. Before the third one, decide whether 0.08 is more or less than halfway to 0.1.
Today we place these decimals on the line together, in this order: first 0.2, then 0.65, then 0.9, and finally 0.04. Each one sits in a slightly trickier spot than the last, so we'll predict where it lands before we drag the marker.
In your maths copy, sketch a number line from 0 to 1 with a mark every 0.1. Then mark each of these decimals on your line and label each mark with its value:
