  5. Whole Numbers Rounding to nearest 10, 100 and 1000 “If It’s 5 or above give it a shove If it’s 4 or below keep it low” To round to the nearest 10 : look at the units digit: - If it is a 0, 1, 2, 3, 4 leave the 10’s digit as it is. - If it is a 5, 6, 7, 8, 9 round the 10’s digit up by 1. To round to the nearest 100 : look at the tens digit: - If it is a 0, 1, 2, 3, 4 leave the 100’s digit as it is. - If it is a 5, 6, 7, 8, 9 round the 100’s digit up by 1.

  6. Whole Numbers Rounding to nearest 10, 100 and 1000 To round to the nearest 1000 : look at the hundreds digit: - If it is a 0, 1, 2, 3, 4 leave the 1000’s digit as itis. - If it is a 5, 6, 7, 8, 9 round the 1000’s digit up by 1.

  7. Whole Numbers Example Round 34 871 to the nearest 100. Round 34871 Round 34 871 Look at the digit in the hundreds position. We need to write down every digit up to this. Look at the digit in the tens position. If this digit is 5 or more then we need to round up the digit in the hundreds position. Solution: 34871 = 34900 (to the nearest 100)

  8. Whole Numbers Complete this table: to the nearest 1000 to the nearest 100 to the nearest 10 37521 38000 37500 37520 274503 275000 274500 274500 7630918 7631000 7630900 7630920 9875 10000 9900 9880 452 0 500 450
