How do kids know comparative vs. superlative?

The signals: than compares two (runs faster than), of-all crowns a group (starts fastest of all). Both signals appear throughout the sentences.

Why do these sentences ask kids to write the form?

Building more quickly from 'quickly' is the actual skill; recognizing it in a list is not. The write-in format is the standard practiced honestly.

How to teach this

Point at the signals: 'than' means comparing two (comparative); 'of all' means a whole field (superlative). Signal first, form second, and the blanks fill themselves.

Watch for: 'More faster' and 'neatlier' are the two classic wrecks: short adverbs take endings, -ly adverbs take more/most, and no adverb takes both. Well is irregular and precious: better, best. 'She sings gooder' is wrong twice; 'she sings better' is the target. Far goes farther, farthest for distance on these sheets. Further is standard for distance too, so it counts as right.
