School ABC Order worksheet for students to practice alphabetical sorting of school-related words.

Let's solve this step by step.

Task:

We are given a list of 20 school-related words and asked to write them in alphabetical order.

---

Step 1: List all the words

Here are the words from the image:

- paperclips
- stapler
- paper
- flag
- calculator
- book
- chalk
- eraser
- glue
- notebook
- games
- whiteboard
- abacus
- marker
- pen
- pencil
- desk
- ruler
- scissors
- computer

---

Step 2: Sort the words alphabetically

We'll go through each word and arrange them starting with A, then B, C, etc.

Let’s group them by first letter:

#### A
- abacus

#### B
- book

#### C
- calculator
- chalk
- computer

#### D
- desk

#### E
- eraser

#### F
- flag

#### G
- games
- glue

#### M
- marker

#### N
- notebook

#### P
- paper
- paperclips
- pen
- pencil
- stapler

Wait — "paper" and "paperclips" both start with p, so we need to compare the second letters:
- paper → p-a-p-e-r
- paperclips → p-a-p-e-r-c-l-i-p-s

They are identical up to the 5th letter. Then:
- paper → ends at 'r'
- paperclips → continues with 'c'

So "paper" comes before "paperclips" because it's shorter and matches up to that point.

Similarly:
- pen → p-e-n
- pencil → p-e-n-c-i-l

So "pen" comes before "pencil"

Also:
- stapler → s-t-a-p-l-e-r

But “stapler” starts with s, which is after p, so it goes later.

Now let’s sort everything properly.

Alphabetical Order:

1. abacus
2. book
3. calculator
4. chalk
5. computer
6. desk
7. eraser
8. flag
9. games
10. glue
11. marker
12. notebook
13. paper
14. paperclips
15. pen
16. pencil
17. ruler
18. scissors
19. stapler
20. whiteboard

Wait — we missed "pen" and "pencil" in earlier steps?

Let’s double-check all 20 words:

Original list:
- paperclips
- stapler
- paper
- flag
- calculator
- book
- chalk
- eraser
- glue
- notebook
- games
- whiteboard
- abacus
- marker
- pen
- pencil
- desk
- ruler
- scissors
- computer

That’s 20 words.

Now, let's go through the full alphabetical list carefully.

Correct Alphabetical Order (Final):

1. abacus
2. book
3. calculator
4. chalk
5. computer
6. desk
7. eraser
8. flag
9. games
10. glue
11. marker
12. notebook
13. paper
14. paperclips
15. pen
16. pencil
17. ruler
18. scissors
19. stapler
20. whiteboard

✔ All 20 words are included.

Let’s verify:
- Starts with A: abacus ✔
- B: book ✔
- C: calculator, chalk, computer ✔
- D: desk ✔
- E: eraser ✔
- F: flag ✔
- G: games, glue ✔
- M: marker ✔
- N: notebook ✔
- P: paper, paperclips, pen, pencil ✔
- R: ruler ✔
- S: scissors, stapler ✔
- W: whiteboard ✔

Order within same letters:
- P: paper → paperclips → pen → pencil? Wait! That’s not correct!

✘ Mistake here!

Let’s fix this.

Critical Step: Sorting "P" Words

Words starting with P:
- paper
- paperclips
- pen
- pencil

Compare:
1. paper → p-a-p-e-r
2. paperclips → p-a-p-e-r-c-l-i-p-s
3. pen → p-e-n
4. pencil → p-e-n-c-i-l

Now, compare first letters: all are p → same.

Second letter:
- paper → a
- paperclips → a
- pen → e
- pencil → e

So:
- "paper" and "paperclips" come before "pen" and "pencil" because 'a' < 'e'

Now compare "paper" vs "paperclips":
- Both start with "paper"
- "paper" ends there
- "paperclips" has more letters: c-l-i-p-s

In alphabetical order, shorter words come before longer ones only if they are prefixes.

So:
- "paper" → p-a-p-e-r
- "paperclips" → p-a-p-e-r-c-l-i-p-s

Since "paper" is a prefix of "paperclips", "paper" comes before "paperclips"

Now, "pen" vs "pencil":
- pen → p-e-n
- pencil → p-e-n-c-i-l

"pen" is a prefix of "pencil", so "pen" comes before "pencil"

So the correct order for P words:
1. paper
2. paperclips
3. pen
4. pencil

✔ Correct.

Now, check S words:
- scissors
- stapler

"scissors" → s-c-i-s-s-o-r-s
"stapler" → s-t-a-p-l-e-r

First letter: s = s
Second letter: c vs t → c < t → so scissors comes before stapler

✔ Correct.

Now, final alphabetical list:

1. abacus
2. book
3. calculator
4. chalk
5. computer
6. desk
7. eraser
8. flag
9. games
10. glue
11. marker
12. notebook
13. paper
14. paperclips
15. pen
16. pencil
17. ruler
18. scissors
19. stapler
20. whiteboard

All 20 words are accounted for.
