FAQ

When do you add '-er' versus '-est' to an adjective?

'-er' is added when comparing two things (e.g., 'taller than'), while '-est' is added when comparing three or more things or indicating the highest degree (e.g., 'the tallest in class').

Are there spelling rules students need to know when adding '-er' and '-est'?

Yes — students learn to double the final consonant for short-vowel adjectives (e.g., big → bigger) and to drop the 'e' before adding the suffix (e.g., nice → nicer), which worksheets address through targeted practice.

How do '-er' and '-est' adjective worksheets connect to 3rd grade ELA standards?

The Common Core Language Standards for Grade 3 include forming and using comparative and superlative adjectives correctly, making these worksheets directly aligned to tested grammar skills.
