Researcher's Briefing:
Welcome to the Prefix Lab! A prefix is a word part added to the beginning of a root word. It changes the word's meaning like a chemical reaction!
Part 1: The Prefix Formulas
Match each prefix to its scientific meaning by drawing a line.
un-
re-
pre-
dis-
again
before
not / opposite
not / away
Part 2: Word Synthesis
Combine the prefix and root word. Then, write the meaning of your new word.
re + heat =
MEANING:
un + kind =
MEANING:
pre + view =

Teaching Tips
Visual Anchors
Encourage students to use different colored highlighters for prefixes (green), suffixes (purple), and root words (yellow) while working.
Verbal Formula
Have students read the word deconstructions aloud. "Re plus heat equals reheat, which means to heat again." This reinforces the phonological and semantic link.
