Understanding decimals is vital for real-life, everyday maths. Phoebe Doyle offers some teacher tips to help your Key Stage 2 child understand what decimals are and how to use this knowledge in calculations.
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.
Never underestimate how much a visual representation of what can otherwise appear to be an abstract concept can help children learn.
When teaching decimal numbers, first review the basics of thousands, hundreds, tens and ones and then introduce (or review) tenths, hundredths and thousandths.
