Tie ten ones together and you make one ten.
A two-digit number has a tens place and a ones place. In 34, the 3 means 3 tens (30) and the 4 means 4 ones.
So 34 is the same as 30 + 4.

Let's try. Bundle 26 sticks into tens and ones.

26 makes 2 tens (two bundles of ten) and 6 ones (six loose sticks).

Let's try. Write the number for "seventy-eight".

Seventy is 7 tens and eight is 8 ones, so it is 78.

To compare two numbers, look at the tens first. More tens means the bigger number.
If the tens are the same, then look at the ones.
We can put numbers in order — from smallest to biggest, or biggest to smallest.

Let's try. Which is bigger, 52 or 58?

Both have 5 tens, so check the ones: 8 is more than 2, so 58 is bigger.

Watch out: do not mix up the digits. 27 and 72 use the same digits, but 72 is much bigger because it has 7 tens.

Where you’ll meet it

Door plates, bus numbers and page numbers all use two-digit numbers. Reading them is real maths.

Ten one-rupee coins make a ten-rupee note — just like ten ones make one ten.

When you play with friends you compare scores to see who got more — bigger number wins.
