1st grade identifying adjectives worksheets

An adjective describes a noun: the red hat, a big dog, three eggs. First graders find the describing word sitting next to the naming word, usually answering what kind or how many.

The kind of sentences you'll get

Underline every adjective in each sentence.

  1. Mom sips hot tea on the steps.

    Answer: hot

  2. The red bird sings to us.
  3. A bug crawls on the wet log.

Every print pulls a fresh set of sentences at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Use the which-one test: say the noun alone (the hat), then ask which hat? The word that answers (red!) is the adjective. First graders love being noun detectives; keep sentences short and let them underline with confidence before you confirm.

Watch for: Adjectives usually come before the noun, but not always: in 'The soup is hot', hot still describes the soup. A, an, and the are their own small group (articles). We don't count them as describing words on these sheets.

Common questions about identifying adjectives

What kinds of adjectives appear in 1st grade?
Colors, sizes, numbers, and feelings: red, big, three, happy. They sit right beside their nouns in short sentences, which makes them findable. Fancier describing words and comparisons (bigger, biggest) arrive in the next grades.
My child underlines the noun instead of the adjective. Help?
Ask the two questions in order: what's the thing? (hat), then what kind of hat? (red). Separating the naming job from the describing job usually clears it up within a few sheets.
