To round numbers to the nearest 10, 100 and 1000. Whole Numbers Rounding to nearest 10, 100 and 1000 Learning Intention To round numbers to the nearest 10, 100 and 1000.

Whole Numbers Rounding to nearest 10, 100 and 1000 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.

Whole Numbers 3470 3500 3000 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 it is. - If it is a 5, 6, 7, 8, 9 round the 1000’s digit up by 1. Example : Round 3467 to the nearest 10, 100, 1000 The nearest 10 : 3467 3470 - look at the units digit : The nearest 100 : 3467 3500 - look at the tens digit : The nearest 1000 :3467 3000 - look at the hundreds digit:

Whole Numbers Rounding to nearest 10, 100 and 1000 Example : Round 18 565 to the nearest 10, 100, 1000 The nearest 10 : 18 565 - look at the units digit : 18 570 The nearest 100 : 18 565 - look at the tens digit : 18 600 The nearest 1000 :18565 - look at the hundreds digit: 19 000
