About this resource

Description

A prefix is a word part added to the beginning of a base word to make a brand new word with a new meaning. This new words worksheet helps 3rd grade students see how prefixes such as un-, re-, pre- and dis- change the meaning of words they already know, a key vocabulary skill for reading unfamiliar words.

In Part A, students read four sentences and look at the underlined word, like unhappy or retell. They fill in the bubble next to the correct meaning and write the base word on the line. In Part B, students choose the correct prefix from a word box to build a new word for each meaning, such as to build again or not fair. Two extra prefixes in the box keep students thinking about what each prefix means. Use it for class practice, homework or a quick check.

What’s Included

  • One printable prefixes worksheet with two parts
  • Four sentence cards with meaning choices
  • A prefix box with four build-a-word meanings
  • An answer key

Why This Prefix Worksheet Helps Kids

First, connecting a prefix to its meaning gives students a tool to figure out new words on their own. Second, writing the base word helps them notice the familiar word hiding inside a longer one. Third, building words from meanings flips the skill around, so students use prefixes actively instead of only recognizing them.

Ideas for Teachers and Parents

After the new words worksheet, start a class prefix chart and add new words as students find them in books. Ask students to act out pairs like tie and untie, or read and reread. These 3rd grade prefix words also make a great spelling list for the week.
