4th Grade Grammar Worksheet: Adjectives and Adverbs - Comparative and Superlative Practice

Of course! Let's solve this 4th-grade grammar worksheet on Comparative and Superlative Adjectives.

---

📚 First, let’s understand the rules from the worksheet:

- Comparative: Used to compare two things.
➤ Add “-er” to the adjective, and use the word “than”.
*Example: tall → taller than*

- Superlative: Used to compare three or more things (or to say something is “the most” of all).
➤ Add “-est” to the adjective, and use the word “the” before it.
*Example: tall → the tallest*

> 💡 Note: For longer adjectives (usually 2+ syllables), we use “more” and “most” instead of -er/-est — but for this worksheet, all the words are short (1 syllable), so we’ll just add -er or -est.
