We often talk of dividing as being the reverse of multiplying, and indeed when dividing fractions this is the case. The way you divide fractions is very similar to the way fractions are multiplied with a simple twist in the middle.
Children may find the easiest way to work this out is by using the column method, where all the numbers are placed in a column, one on top of the other. It is vital that they remember that the decimal points of each number must line up. Once they’ve worked out using pencil and paper, let them check on a calculator as using decimals accurately on a calculator is an important real life skill too.
Since practice makes perfect, one effective method is to use your text book and write on paper all of the concepts along with equations that represent that concept. Keep each concept on a different sheet. Take notes and write down your opinion for every equation or algebra concept. You may not like it at first, but the more you practice and use this personal algebra notebook the better for you. You must be patient because at first it might seem like you are never going to be able to figure out how all of these numbers plug into one and other, so do not rush, remember that learning algebra takes time.
Children will be learning at school how to round up decimals to the nearest whole number. A fun way to practise this at home is to use regular dominos and establish that each piece is a decimal number (so a domino one with 3 dots and 4 dots is 3.4). Encourage them to play with the dominos, but with the rule that they can only, for example, join 2 dominos that are within 1.5 of each other. This will really get them thinking about what each decimal point represents. A number line can also be useful when rounding decimals.
