## 📌 Understanding the Rules

The worksheet gives two clear rules for rounding:

> Rule 1: Look at the digit to the right of the rounding digit.
> If it is 1, 2, 3, or 4 → Do NOT change the rounding digit. All digits to the right become 0.

> Rule 2: If the digit to the right is 5, 6, 7, 8, or 9 → Round up the rounding digit by 1. All digits to the right become 0.

## ✔ Part 1: Round to the nearest 10 (Numbers under 100)

Here, we are rounding to the tens place, so we look at the ones digit (the digit to the right of the tens).

Let’s go one by one:

1.) 47 → Ones digit = 7 → Rule 2 → Round up → 50

2.) 51 → Ones digit = 1 → Rule 1 → Keep same → 50

3.) 65 → Ones digit = 5 → Rule 2 → Round up → 70

4.) 22 → Ones digit = 2 → Rule 1 → Keep same → 20

5.) 43 → Ones digit = 3 → Rule 1 → Keep same → 40

6.) 99 → Ones digit = 9 → Rule 2 → Round up → 100

7.) 86 → Ones digit = 6 → Rule 2 → Round up → 90

8.) 28 → Ones digit = 8 → Rule 2 → Round up → 30

9.) 77 → Ones digit = 7 → Rule 2 → Round up → 80

10.) 24 → Ones digit = 4 → Rule 1 → Keep same → 20

11.) 55 → Ones digit = 5 → Rule 2 → Round up → 60

12.) 21 → Ones digit = 1 → Rule 1 → Keep same → 20

13.) 21 → Same as above → 20

14.) 56 → Ones digit = 6 → Rule 2 → Round up → 60

15.) 94 → Ones digit = 4 → Rule 1 → Keep same → 90

16.) 88 → Ones digit = 8 → Rule 2 → Round up → 90

17.) 11 → Ones digit = 1 → Rule 1 → Keep same → 10

18.) 16 → Ones digit = 6 → Rule 2 → Round up → 20

19.) 15 → Ones digit = 5 → Rule 2 → Round up → 20

20.) 33 → Ones digit = 3 → Rule 1 → Keep same → 30

## ✔ Part 2: Round to the nearest 10 (Larger numbers — 3-digit numbers)

Same rule applies! We’re still rounding to the nearest 10, so again, look at the ones digit.

1.) 407 → Ones digit = 7 → Rule 2 → Round up → 410

2.) 451 → Ones digit = 1 → Rule 1 → Keep same → 450

3.) 635 → Ones digit = 5 → Rule 2 → Round up → 640

4.) 225 → Ones digit = 5 → Rule 2 → Round up → 230

5.) 432 → Ones digit = 2 → Rule 1 → Keep same → 430

6.) 929 → Ones digit = 9 → Rule 2 → Round up → 930

7.) 806 → Ones digit = 6 → Rule 2 → Round up → 810

8.) 328 → Ones digit = 8 → Rule 2 → Round up → 330

9.) 677 → Ones digit = 7 → Rule 2 → Round up → 680

10.) 245 → Ones digit = 5 → Rule 2 → Round up → 250

11.) 551 → Ones digit = 1 → Rule 1 → Keep same → 550

12.) 218 → Ones digit = 8 → Rule 2 → Round up → 220

13.) 291 → Ones digit = 1 → Rule 1 → Keep same → 290

14.) 556 → Ones digit = 6 → Rule 2 → Round up → 560

15.) 394 → Ones digit = 4 → Rule 1 → Keep same → 390

16.) 888 → Ones digit = 8 → Rule 2 → Round up → 890

17.) 111 → Ones digit = 1 → Rule 1 → Keep same → 110

18.) 616 → Ones digit = 6 → Rule 2 → Round up → 620

19.) 125 → Ones digit = 5 → Rule 2 → Round up → 130

20.) 336 → Ones digit = 6 → Rule 2 → Round up → 340

✔ Summary: Always look at the digit immediately to the right of your target place (here, the tens place). If it’s 5–9 → round up. If it’s 0–4 → keep the digit the same. Then make all digits to the right zero.
