Teacher's field guide

What Students Need to Do: Students spot a familiar root or base word and any prefix or suffix in an unfamiliar word. They use those parts to work out a likely meaning, then check if it fits the sentence.
What Mastery Looks Like: A student breaks unhelpful into un, help, and ful, then explains that it means not helpful. If a guessed meaning does not fit the sentence, they try again.
Common Misconceptions: Students may think every word starting with re has a prefix, even red. They may read the prefix but ignore the base word, so they mistake preheat for 'heat again.'
How to Assess It: Write, 'Preheat the oven before putting in the cookies.' Ask students to circle the prefix, underline the base word, and explain what preheat means.

Lesson moves

Give pairs cards labeled re, un, pre, heat, pack, and view; have them build real words and explain each meaning.
Ask students to write how the parts of reusable help them figure out its meaning, then use it in a sentence.
Play word-part bingo: call out 'can be used again,' and have students cover reusable on their cards.
Bring a package marked reusable; have students identify re, use, and able, then explain what the label tells shoppers.
