Maths Support Week 4 Summer 1

Next week the children will be focussing on rounding within their Maths. The children will round decimals with two decimal places to the nearest whole number and to one decimal place. They will also read, write, order and compare numbers with up to three decimal places.

Rounding to a given number of places

Counting decimal places

Decimal places are counted from the decimal point:

So, the number 5.1492 has four decimal places, while 4.34 has two decimal places.

To round a number to a given number of decimal places, look at the number in the next decimal place:

  • If it’s less than 5, round down
  • If it’s 5 or more, round up


Round 9.6371 to 2 decimal places

This means we need 2 digits after the decimal point.

Because the next digit 7, is more than 5, we round the 3 up.

9.6371 = 9.64 ( 2 decimal places).
