What children learn in Level 9

  • Welcome to the Root Temple! Long words were built from old pieces. Find the pieces, and you can work out the meaning. Prefixes come first.
  • Some prefixes tell how. Anti means against, so antifreeze works against freezing. Co means together, so a coauthor writes with someone.
  • Some tell where or when. Ex means out, so you exhale, or breathe out. Inter means between, so an interstate road runs between states.
  • Be careful: a word can start with those letters and not have the prefix. In the word comb, c o isn't a prefix. Check that the rest still means something.

Georgia's K-12 English Language Arts Standards:

  • 5.L.V.2.a β€” Deconstruct words using knowledge of Greek and Latin roots, root words, and affixes to determine meaning. (I)
