What it is about memorizing multiplication tables that make my kids throw their pencil across the room and shout, “I hate math?” It is because, unlike spelling or vocabulary, numbers don’t create pictures for us. Multiplication tables are strings of seemingly random numbers that our children are expected to not only remember, but keep in order and in context with the numbers they are multiplying by.
Children usually start to learn about decimals in Year 4. The first thing children need to know is that a decimal is A PART of a whole. A good way to explain this is to show them an empty hundred number square / chart.
Long Division. There are different methods for dividing multi-digit numbers (long division). One way is a combination of estimation/ trial and error and multiplication. There is also a commonly used algorithmic method that is well explained and illustrated here at mathisfun.com.
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.
