About this worksheet

Sentences with a missing word. Pick the word with the prefix or suffix that fits.

What kids practice

A prefix is a word part added to the start of a word, and a suffix is added to the end. Each one changes the meaning in a way you can learn: un- means not, so unhappy means not happy. -ful means full of, so helpful means full of help. Knowing these parts helps kids read and understand longer words.

Watch for

  • Reading the prefix as part of the base word, like unhappy as "un-hap-py" without seeing happy.
  • Mixing up -ful and -less, which mean almost opposite things.
  • Thinking every word that starts with re or un has a prefix, like read or uncle.

It's free to print, with Fewer, Standard or More on the page and an answer key. See the full prefixes and suffixes guide for 2nd grade.
