Prefixes (age 7+)

PROCEDURAL

English›Spelling & Word Study|Ages 7—10|ID: mt_T6nrrf2K43

Spell words with a range of prefixes (dis-, mis-, un-, re-, pre-, anti-, auto-, super-) understanding how each prefix modifies the root word's meaning without changing its spelling

Mastery Evidence

Spell words with prefixes dis-, mis-, re- correctly without altering the root (e.g., disappoint, misspell, return)
Add prefixes un-, pre-, anti-, auto-, super- to root words and use the new word in a sentence (e.g., unhappy, preview, autograph)
Explain how a prefix changes the meaning of a root word (e.g., 'dis-' means 'not' or 'opposite of')

Assessment Prompt

“If [child] sees a word starting with "dis-," "mis-," or "pre-," can they work out what the word means and spell it correctly by thinking about the prefix?”
