Teacher's field guide

What Students Need to Do: Students spot familiar prefixes, suffixes, and roots in words. They use those parts to read unfamiliar words and spell words they hear.
What Mastery Looks Like: A student can read unhelpful by spotting un-, help, and -ful, then explain what the word means. They can spell reusable and know to drop the final e in use before adding -able.
Common Misconceptions: Some students split replay as rep-lay and miss the meaning of re-. Others write reuseable, keeping the e in use before adding -able.
How to Assess It: Give students an exit ticket with unhelpful and replayed. Have them mark the word parts, read each word to a partner, then spell both words from dictation.

Lesson moves

Give pairs prefix, root, and suffix cards to build, read, and write words such as unhelpful and replayed.
Ask, 'How do re- and -ed change play in replayed?' Have students explain the meaning in one sentence.
Play a word-building relay: call out 'without care,' then have teams build careless with cards and spell it without them.
Show a reusable shopping bag label; students mark the word parts, then write refillable on a bottle label.
