We have been learning how many tens there are in numbers.
In the number sixty there are six tens.
There are some clues in the word sixty that can help us to remember how many tens there are... 'ty' means 'lots of ten' and we can also see the word six so it is easy to know that there are 6 lots of ten in sixty.
In sixty-three there are 6 lots of ten and 3 ones.
We can use equipment to show this.
