Count with tens and ones

Hey! This way!

Place value helps us to work out the value of a digit depending on its place or position in a number. But when we get to nine we run out of numbers.

Ah, don't worry little fella.

Now we're going to need something even bigger.

Tens!

Oh phew! There you are!

Now you can see where the different values are placed.

The tens are at the back and the ones out in front

And when we get to 20…

Uh oh! Here we go again!
