Decimal Numbers (Year 5)

In KS2 Maths, kids learn about decimal numbers. In Year Five, they explore the value of digits in decimals, like tenths and hundredths. Plus, they practice adding and subtracting decimals. Rounding decimals up or down becomes a breeze, and they get comfy with sums involving decimal measurements such as metres/cm or £/pence.

Decimal numbers are smaller than one and come after a decimal point. They're like another way of writing fractions. For example, a quarter of pizza as a fraction is 1/4, but as a decimal, it's 0.25. The 2 in 0.25 means 2 tenths, and the 5 is 5 hundredths.

Can you spot the difference between tenths and hundredths? How about rounding a number to two decimal places? Test your decimal number skills by playing this quiz!
