How many tens are there in 56

One, tens, hundreds

We'll deal with ones, tens, and hundreds in this article. The following content is offered:

  • A Explanation how to work with units, tens and hundreds in mathematics and how to enter these in a place value table.
  • There will be several Examples presented with numbers.
  • You get tasks or. Exercises to train yourself. With sample solutions.
  • A video area shows Videosthat are pertinent to this topic.
  • A Question and answer area at the end of the article with typical questions on this topic.

From the 2nd grade onwards, pupils deal with slightly larger numbers. You often look at the ones, tens and hundreds. However, in order to be able to understand this well, one should already have a few basics of mathematics. You should therefore master simple plus and minus tasks as well as number pyramids.

One, tens and hundreds: explanation

We'll deal with larger numbers in a moment and how to enter them on a place value table. To do this, let's take a quick look at how numbers are actually structured. Let's start counting up to 9, starting with 0.

We have now reached 9. But now the counting changes. The last digit then becomes a 0 and a 1 is added at the front. After the 9, the 10 follows.

And from then on the counting starts again at the very back:

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

We now have the 9 at the very back. As soon as this is reached and we continue counting, the 1 becomes a 2 at the front and it starts again from the 0 at the back.

  • 20
  • 21
  • 22
  • 23
  • 24
  • 25
  • 26
  • 27
  • 28
  • 29

This counting continues up to 99. Then it goes one place further up, we reach 100.

One, tens and hundreds: examples

We have just dealt with counting to 100. We would now like to break down numbers and enter them on a place value table. How this looks then depends on the size of the number. The numbers from 0 to 9 only occupy the ones digit. The numbers from 10 to 99 occupy the ones place and the tens place. And from the number 100 onwards, the hundreds digit is also used. We will now look at examples of this.

example 1:

The numbers 80, 12, 6, 34, 56, 82, 100 and 12 should be entered in a place value table with ones, tens and hundreds.

Solution:

Example 2:

Numbers should be formed:

  • 2 Z + 5 E
  • 3 Z + 2 E
  • 7 Z + 3 E
  • 7 E.
  • 1 H + 0 Z + 3 E.

Solution:
