This rounding worksheet helps students practice rounding two-digit numbers to the nearest ten, building essential place value understanding.

Let's solve the rounding problem step by step.

Task:

Round each 2-digit number to the nearest ten.

We follow the rule:
- If the ones digit is less than 5, round down (to the lower ten).
- If the ones digit is 5 or more, round up (to the higher ten).

Left Column:

| Number | Rounded to nearest ten |
|--------|-------------------------|
| 24 | Ones digit = 4 → less than 5 → round down → 20 ✔ |
| 43 | Ones digit = 3 → less than 5 → round down → 40 |
| 62 | Ones digit = 2 → less than 5 → round down → 60 |
| 59 | Ones digit = 9 → 9 ≥ 5 → round up → 60 |
| 69 | Ones digit = 9 → 9 ≥ 5 → round up → 70 |
| 26 | Ones digit = 6 → 6 ≥ 5 → round up → 30 |
| 42 | Ones digit = 2 → less than 5 → round down → 40 |
| 83 | Ones digit = 3 → less than 5 → round down → 80 |
| 74 | Ones digit = 4 → less than 5 → round down → 70 |

Right Column:

| Number | Rounded to nearest ten |
|--------|-------------------------|
| 4 | This is a single-digit number, but we still round to nearest ten:
4 is closer to 0 than to 10 → 0 (but note: in some contexts, it might be left as 4, but since it says "round to nearest ten", and 4 is between 0 and 10, nearest ten is 0) → 0 |
| 78 | Ones digit = 8 → 8 ≥ 5 → round up → 80 |
| 87 | Ones digit = 7 → 7 ≥ 5 → round up → 90 |
| 18 | Ones digit = 8 → 8 ≥ 5 → round up → 20 |
| 32 | Ones digit = 2 → less than 5 → round down → 30 |
| 9 | Single-digit: closest ten is 0 → 0 |
| 19 | Ones digit = 9 → 9 ≥ 5 → round up → 20 |
| 28 | Ones digit = 8 → 8 ≥ 5 → round up → 30 |
| 91 | Ones digit = 1 → less than 5 → round down → 90 |

Explanation:

- We look at the ones digit.
- If it’s 0–4, we round down.
- If it’s 5–9, we round up.
- For numbers like 4 and 9, even though they are single-digit, we still round to the nearest ten: 4 rounds to 0, 9 rounds to 10? Wait — let’s double-check that!

Wait! There's a potential confusion here.

> Important: The number 9 — which ten is it closest to?
- 9 is between 0 and 10.
- Distance to 0: 9
- Distance to 10: 1
→ So 9 is closer to 10 than to 0.

So, 9 should round to 10, not 0.

Similarly, 4:
- Distance to 0: 4
- Distance to 10: 6
→ Closer to 0 → rounds to 0

But for 9, since it’s only 1 away from 10, and 9 away from 0, it rounds to 10.

So correction:

- 9 → 10
- 4 → 0

Now update:

| Number | Rounded |
|--------|---------|
| 4 | 0 |
| 9 | 10 |

Yes! That makes sense.

So final corrected answers:

Right Column:

- 4 → 0
- 78 → 80
- 87 → 90
- 18 → 20
- 32 → 30
- 9 → 10
- 19 → 20
- 28 → 30
- 91 → 90

Summary of Rounding Rule:

- Look at the ones digit.
- If ≤ 4, round down.
- If ≥ 5, round up.
- For single digits: apply same logic based on proximity to tens.

✔ All done!
