What are the irregular comparatives?

Good/better/best, bad/worse/worst, far/farther/farthest, and little/less/least. They ignore the -er/-est machinery entirely, so they're learned as small famous families. Fourth grade items mix them in once the regular system is automatic. For distance these sheets use farther; further means the same thing to many writers, so count it right if your child writes it.

Is "the faster of the two" really correct?

Yes, and it surprises people. With exactly two, careful English uses the comparative: the faster runner, the taller twin. With three or more, the superlative takes over. It's a detail that makes students feel like insiders, which is half the fun of teaching it.

4th grade comparative and superlative adjectives worksheets

Fourth graders work the full system: -er/-est with spelling changes, more/most for longer adjectives, and the irregulars good/better/best and bad/worse/worst. The sentence's comparison cue (than, of the two, in the whole school) always points to the answer.

How to teach this

Push on precision. "Of the two runners, she is the faster" sounds strange to many adults, which makes it a fun correctness conversation with 4th graders. Add the irregulars (good/better/best, bad/worse/ worst, far/farther/farthest) and let students prove each answer by counting what's being compared.

Watch for: Long adjectives use more and most instead of -er and -est: more colorful, most interesting, never colorfuler. Never double up: 'more taller' and 'most fastest' are always wrong.
