In KS2 Maths children will come to understand how the place values of digits in numbers change depending on their position. In Year Five children should have a good grasp of thousands, hundreds, tens, units, tenths and hundredths and they will now become familiar with hundred thousands. They should also be aware of the equivalent values of these numbers (eg 10 x 10 = 100, or 10 x 100 = 1,000) and also be able to write numbers using both words and digits.

The values of digits change depending on their place in a number. A two, for example, can be worth 2 units, 2 tens, 2 hundreds or 2 thousands, the equivalent of 2, 20, 200 and 2,000. So, which number would be the equivalent of 4 hundreds, 3 tens and 5 units? The answer is 435.
