How we explain it

Children can open this short lesson before they practice.

  1. Roots carry meaning: tele (far), therm (heat), graph (write), bio (life).
  2. Prefixes change meaning: mis- (wrongly), re- (again), un- (not). Suffixes change the word’s job.
  3. Idioms are figures of speech that don’t mean exactly what they say.

Example: The prefix mis- means “wrongly.” What does misspell mean? Take the base word: spell. Add the meaning of mis-. Answer: spell wrongly
