In KS2 Maths children will spend a lot of time doing multiplication and division. In Year Six children should be well versed in their times tables and also in basic multiplication and division. In addition they should be familiar with terms such as 'multiple', 'factor' and 'product'. As a part of their multiplication and division, Year Six students will be expected to be able to convert remainders into fractions and decimals. They should also be able to express fractions as decimals and vice versa.
Multiplication and division (specifically) use remainders. Remainders are parts of a number that are left over. As an example, I have 4 cats and 10 cat treats. I can only give each cat 2 treats each, which means I will have 2 treats left over. The 2 left can't be divided by 4 as it is below 4, therefore the 2 is a 'remainder'. Remainders can be converted into fractions and decimals like so:
10 ÷ 4 = 2 r2 or 2.25 or 21⁄4
