Year 5 fluency and precision worksheet for reading and writing numbers, including word conversion, expanded form, and number line activities.

Let’s go step by step to solve each part of the worksheet.

---

Part 1: Write numbers in words

We are given numbers and need to write them out as words, following the example:

> 18,643 → Eighteen thousand, six hundred and forty three

Remember:
- Break the number into thousands and the rest.
- Use “and” before the last part if it’s under 100 (like “forty three”).
- Don’t forget commas in writing — but we don’t write the comma in words.

Let’s do each one:

✔ 54,980
→ Fifty-four thousand, nine hundred and eighty

✔ 73,521
→ Seventy-three thousand, five hundred and twenty-one

✔ 89,735
→ Eighty-nine thousand, seven hundred and thirty-five

*(Note: In British English, we often say “and” before the tens/units. We’ll follow that style since the example uses it.)*

Part 2: Write the number from expanded form

This means adding up all the parts.

✔ First line:
400,000 + 20,000 + 3,000 + 700 + 40 + 1
= 423,741

Check:
400k + 20k = 420k
+3k = 423k
+700 = 423,700
+40 = 423,740
+1 = 423,741 ✔️

✔ Second line:
520,000 + 40,000 + 2,000 + 900 + 30 + 8
= 562,938

Check:
520k + 40k = 560k
+2k = 562k
+900 = 562,900
+30 = 562,930
+8 = 562,938 ✔️

✔ Third line:
680,000 + 30,000 + 8,000 + 300 + 90 + 3
= 718,393

Check:
680k + 30k = 710k
+8k = 718k
+300 = 718,300
+90 = 718,390
+3 = 718,393 ✔️

Part 3: Fill in empty boxes in the number line

These are sequences where numbers increase by 1 each time (since they’re consecutive).

✔ First row:
Starts at 351,207 and ends at 351,212
So we fill in between:

351,207 → 351,208 → 351,209 → 351,210 → 351,211 → 351,212

✔ Second row:
Given: [ ] , 820,630 , [ ] , [ ] , 820,633 , [ ]

Since 820,630 to 820,633 is 3 steps forward, each box increases by 1.

So:
Before 820,630 → 820,629
After 820,630 → 820,631
Then → 820,632
Then 820,633
Then → 820,634

Full sequence:
820,629, 820,630, 820,631, 820,632, 820,633, 820,634

✔ Third row:
Given: [ ] , [ ] , [ ] , 934,780 , [ ] , [ ]

Again, increasing by 1 each time.

So before 934,780:
→ 934,779
→ 934,778
→ 934,777

After 934,780:
→ 934,781
→ 934,782

Full sequence:
934,777, 934,778, 934,779, 934,780, 934,781, 934,782

Final Answer:

Words for numbers:
- 54,980 → Fifty-four thousand, nine hundred and eighty
- 73,521 → Seventy-three thousand, five hundred and twenty-one
- 89,735 → Eighty-nine thousand, seven hundred and thirty-five

Expanded form to standard number:
- 400,000 + 20,000 + 3,000 + 700 + 40 + 1 → 423,741
- 520,000 + 40,000 + 2,000 + 900 + 30 + 8 → 562,938
- 680,000 + 30,000 + 8,000 + 300 + 90 + 3 → 718,393

Number lines filled:

First row:
351,207, 351,208, 351,209, 351,210, 351,211, 351,212

Second row:
820,629, 820,630, 820,631, 820,632, 820,633, 820,634

Third row:
934,777, 934,778, 934,779, 934,780, 934,781, 934,782
