How to teach this

Use real objects first: two pencils, then three. Which is longer? Which is longest? The physical two-versus-three moment is the entire concept, and the endings attach themselves to it naturally. On worksheets, train kids to hunt for the clue words before choosing: "than" and "of the two" mean -er; "of all" means -est.

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.
