Educational worksheet for learning how to add -ed and -ing to verbs, with examples and exercises.

Let’s solve this step by step.

---

## 📚 Part 1: Understanding the Rules

The worksheet gives two rules:

✔ Rule for adding -ed:

> Change y to i, then add -ed.
*(Applies when a word ends in “y” and is preceded by a consonant — like “spy”, “cry”, etc.)*

✔ Rule for adding -ing:

> Just add -ing.
*(Usually straightforward — but watch out for exceptions!)*

⚠️ Warning: *“Be careful — there are some that don’t follow the rules!”*
This means we need to be alert for irregular verbs or words where the rule doesn’t apply (like “dried”, “emptied”, “replying”, “studying” — which are given as clues).

## 🧩 Part 2: Fill in the Missing Words

We’ll go row by row using the rules and clues.

---

1. spy

- Add -ed: spy → change y to i → spied
- Add -ing: just add -ing → spying

✔ spied, spying

---

2. cry

- Add -ed: cry → change y to i → cried
- Add -ing: just add -ing → crying

✔ cried, crying

---

3. copy

- Add -ed: copy → change y to i → copied
- Add -ing: just add -ing → copying

✔ copied, copying

---

4. (blank) → dried

We’re given “dried” under “add ed”. What base word becomes “dried”?
→ dry (dry → dri + ed = dried)

So, word = dry

Add -ing: dry → drying

✔ dry, drying

---

5. worry

- Add -ed: worry → change y to i → worried
- Add -ing: just add -ing → worrying

✔ worried, worrying

---

6. (blank) → replying

Given “replying” under “add ing”. What base word?
→ reply (reply → replying)

Add -ed: reply → change y to i → replied

✔ reply, replied

---

7. scurry

- Add -ed: scurry → change y to i → scurried
- Add -ing: just add -ing → scurrying

✔ scurried, scurrying

---

8. (blank) → emptied

Given “emptied” under “add ed”. Base word = empty

Add -ing: empty → emptying

✔ empty, emptying

---

9. stay

- Add -ed: stay → stayed *(Note: “ay” ends in vowel + y → we do NOT change y to i! So this is an exception to the rule.)*
- Add -ing: just add -ing → staying

✔ stayed, staying

---

10. (blank) → studying

Given “studying” under “add ing”. Base word = study

Add -ed: study → change y to i → studied

✔ study, studied

---

11. annoy
