Rounding large numbers We have just added three more sets of worksheets on rounding large numbers, suitable for Year 5. The first two look at rounding numbers with 5 digits (including decimals) to the nearest 10 and 100. The third set looks at rounding the same 6-digit number to the nearest 100, 1 000 and 10 000. This is very similar to the style of question found on the SAT Papers in Year 6. Go to Year 5 Number: Rounding
