Comparison of Adjectives interactive worksheet - Free Printable

I need to complete these comparative adjective sentences. Let me work through each one carefully, applying the rules for forming comparatives in English.

Rules for comparatives:
- Short adjectives (1-2 syllables): add -er (big → bigger)
- Adjectives ending in -y: change y to i and add -er (happy → happier)
- Long adjectives (3+ syllables): use "more" + adjective (interesting → more interesting)
- Irregular forms: good → better, bad → worse

Let me solve each sentence:
