The lesson

Numbers from 10 to 99 have two digits. The first digit shows tens. The second digit shows ones. One hundred is special: it has three digits.

Tap each dot and count out loud.
1 group of ten and 6 more make 16.
Try it together

Mia has 52 stickers. She counts 5 tens and 2 ones. She writes the number 52.

Good to know

Look at the first digit for tens. Look at the second digit for ones. That tells you the whole number.

Two-digit numbers have a tens digit and a ones digit.
