1st Grade Identifying Prepositions Worksheets

Prepositions are little where-words: in, on, under, by. They tell where something is or where it's going. First graders find the where-word in short sentences, a skill their hands already know from putting toys in boxes and cups on tables.

The kind of sentences you'll get

Underline every preposition in each sentence.

  1. We walk on a long path.

    Answer: on

  2. Mom hugs me at the door.
  3. My mom reads to us at night.

Every print draws a fresh mix of sentences at this level, so a make-up test or a second sibling gets a different 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

Act it out with any small toy: put the block ON the book, IN the cup, UNDER the chair, and say each little word with drama. Then hunt the same words in sentences. Position words stick fastest when the body does the positioning first.

Watch for: Many prepositions are tiny words (in, on, at, of), so students read past them. Small doesn't mean unimportant. A preposition always has a partner noun after it: under the porch, with my friend. If there's no partner, it's working as a different part of speech.

Common questions about identifying prepositions

Isn't preposition a big word for 1st grade?
The label is big; the idea is tiny. Call them where-words and first graders find them easily: in, on, under, by, up. The formal name can wait; the finding is what the grade needs.
Which prepositions should we practice first?
The physical ones a child can demonstrate: in, on, under, by, to. Time prepositions like during or abstract ones like about belong to later grades. If your child can act it out with a stuffed animal, it's fair game now.
