We'll see in a moment how to display and enter decimal numbers on the number line. You should be able to handle numbers a bit. If the following topics do not mean anything to you, please read them first: Plus and minus problems up to 20, addition and subtraction up to 100 and converting fractions into decimal numbers. Those who already know this can read on right away. I recommend all others to read the articles mentioned first.

Explanation of the number line and decimal numbers

If you deal with the number line in school, then at the beginning you enter natural numbers on it. It can look like this, for example:

Of course, you can also display decimal numbers - that is, floating point numbers - on a number line. Let's take the following number line:

As you can see, decimal numbers between 0 and 1 are entered here. Between 0 and 1 there are 9 lines at equal intervals. For each line you have to count 0.1. The basic rule here is that an "even series" of decimal numbers must be created here. Note: The arrow pointing to the right as shown in the next graphic is often left out, please don't be surprised.

A number line with decimal numbers can also look a little different:

Here, too, the steps between 0 and 0.1 as well as between 0.1 and 0.2 and also between 0.2 and 0.3 must be the same size. Between 0.1 and 0.2 these would be the decimal numbers

  • 0,11
  • 0,12
  • 0,13
  • 0,14
  • 0,15
  • 0,16
  • 0,17
  • 0,18
  • 0,19

If you look closely, you will notice that the small line at 0.15 is slightly larger. This is also the case with 0.25 and also previously with 0.05. There are also three arrows above the number line. The corresponding decimal numbers (point numbers) should now be specified for these. It would then look like this:
