Teacher's field guide

What Students Need to Do: Students find the base word and a prefix or suffix in a longer word. They use both parts to figure out what the word means.
What Mastery Looks Like: A student can explain that redo means do again and careless means without care. They can check whether that meaning fits the sentence.
Common Misconceptions: Students may think unhappy means very happy instead of not happy. They may think careless means careful or mistake the re in red for a prefix.
How to Assess It: Write, “Please refill the cup” and “That was a careless mistake.” Ask students to underline each base word and explain what each longer word means.

Lesson moves

Give pairs cards for happy, kind, help, and care, plus tiles for un, ful, and less; have them build words and explain their meanings.
Ask, “How does a careless choice differ from a careful choice?” Have partners explain what each ending adds.
Play a word sort: students place redo, replay, unhappy, and unsafe under cards labeled “again” or “not.”
Show a water station sign that says “Refill bottles” and ask students what refill tells them to do.
