A digit is one of the symbols we use to make our numbers. We have ten of them: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. We can use them by themselves (for wxample, I have 2 cats) or we can put them together to make bigger numbers (for example, there are 284 pupils in our school - this is a 3-digit number). When we put them together, it depends on where we put them as to what they stand for. For 284, '2' stands for 2 hundreds (200), '8' stands for 8 tens (80) and '4' stands for 4 units (4). Where they are in a number will tell you what their place value is (or what they are worth).

Division is where you find out how many lots of one number there are in another. You use this when you are sharing and you want to see how many of something each person gets, or when you are grouping and you want to find out how many of something there will be in a group.
