3rd Grade Core Spelling

3rd Grade Core Spelling covers 7 ordered units: it opens with prefixes and suffixes as meaning-carrying word parts, adds the spelling changes a suffix can trigger, turns to possessive apostrophes, applies syllable-based strategies to longer words, and closes with homophones and an early look at root word families.

Prefix Words and Suffix Words introduce word parts that attach to a base and change its meaning or use; Suffix Spelling Changes follows immediately after because it teaches what happens to that base — dropping a final e, doubling a consonant, or changing y to i — once a suffix is added. Possessive Words then isolates a separate apostrophe convention before the sequence turns to word length itself: Multisyllabic Words asks children to break down and rebuild longer words using that same base-and-part thinking. Homophones and Commonly Confused Words shifts to choosing the correct spelling by meaning rather than sound, and Root Word Families closes the sequence with recognizable roots — act, form, port, and sign — that anticipate the deeper Greek and Latin root study 4th Grade introduces.

Where to begin: Begin with Prefix Words if adding word parts to a base is new. Suffix Words and Suffix Spelling Changes follow directly, since spelling a suffixed word correctly depends on the base-word habits those first two units build; the possessive, multisyllabic, homophone, and root-word-family units later in the sequence each teach a distinct skill, so continuing in order keeps that foundation in place.
