4th grade suffixes worksheets

The kind of sentences you'll get

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

• Choose the word. Circle the letter of the word with the correct suffix. 10 questions per page.

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

How to teach this

Sort the suffixes by the job they create: -ness, -ment, and -ion build nouns; -able and -ous build adjectives. Then test it in reverse: if the sentence needs a thing, a noun-making suffix wins (payment, not payable). That sentence-slot reasoning is the bridge to the Greek and Latin roots coming in later grades.

Watch for: -ful and -less are opposites on the same base: hopeful means full of hope, hopeless means without it. A suffix can change a word's job in the sentence: teach is an action, teacher is a person.

Common questions about suffixes

What do -ness, -ment, and -ion have in common?

All three build nouns: kind becomes kindness, excite becomes excitement, celebrate becomes celebration. When a sentence needs a thing rather than an action or description, one of these endings usually supplies it.

How do suffixes help with big words on tests?

The ending announces the word's job before the whole word is even decoded. Seeing -able promises an adjective meaning can be done; seeing -ion promises a thing or process. Readers who use those signals handle unfamiliar vocabulary with far less guessing.
