This week we have continued our topic on Decimals. We looked at how to round decimals with 1 decimal place to the nearest whole number.

They learnt to use the word “integer” as an alternative to “whole number”. The children were able to make links to rounding to the nearest 10, 100 and 1,000 studied in the Autumn term. We used number lines to help them to see which whole numbers a decimal number lies between.

They then considered which whole number the decimal number is nearer to, by looking at the digit in the tenths column. Using the same convention as in their earlier rounding, a number with a 5 in the tenths column, although exactly halfway between integers, rounds to the greater integer.
