Activity 01
Word Building Stations: Prefix and Suffix Cards
Prepare cards with base words, prefixes un- and re-, and suffixes -ing and -ed. Students draw a base word and add one affix to create a new word, then use it in a sentence. Rotate stations for prefix focus, suffix focus, and mixed practice. Groups share three examples with the class.
Predict the meaning of a new word by analyzing its prefix or suffix.
Facilitation TipDuring Word Building Stations, circulate to ask each pair: 'How does the prefix/suffix change the base word's meaning?' This pushes students beyond simple word creation to deeper analysis.
What to look forGive students a card with a base word (e.g., 'happy', 'do', 'play', 'walk'). Ask them to write one new word using a prefix or suffix learned today and draw a picture representing the new word's meaning.

Activity 02
Pair Prediction Game: Mystery Words
Pairs receive word cards with affixes highlighted, like un + happy. They predict and discuss meanings before checking a dictionary poster. Partners then write a short sentence and swap to guess each other's words. Collect sentences for a class word wall.
Construct new words by adding common prefixes or suffixes to base words.
Facilitation TipIn the Pair Prediction Game, provide sentence frames like 'I think _____ means _____ because _____.' This structures peer conversation and accountability.
What to look forDisplay a list of words: 'unhappy', 'redo', 'playing', 'walked'. Ask students to identify the base word, the prefix or suffix, and explain how the added part changed the meaning. Use thumbs up/down for quick comprehension checks.

Activity 03
Whole Class Sort Relay: Prefix vs Suffix
Divide class into two teams. Call out words like 'running' or 'unpack'; teams race to sort them into prefix or suffix hoops on the floor, explaining changes. Correct sorts earn points; review errors together.
Differentiate how a prefix changes a word's meaning compared to a suffix.
Facilitation TipSet a timer for the Whole Class Sort Relay to keep energy high and prevent over-thinking; speed encourages quick recognition of patterns.
What to look forPose the question: 'How is adding 'un-' to 'kind' different from adding '-ing' to 'kind'?' Guide students to explain that 'unkind' means not kind, while 'kinding' isn't a word we use, but if it were, it might mean being kind right now. Focus on the meaning change.

Individual Journal Extension: My New Words
Students select five base words from a list, add one prefix or suffix to each, and illustrate the meaning change. They write a sentence and share one with a partner for feedback before adding to journals.
Predict the meaning of a new word by analyzing its prefix or suffix.
Facilitation TipHave students highlight base words in their Individual Journals to reinforce tracking the root meaning before adding affixes.
What to look forGive students a card with a base word (e.g., 'happy', 'do', 'play', 'walk'). Ask them to write one new word using a prefix or suffix learned today and draw a picture representing the new word's meaning.

Generate Complete Lesson→A few notes on teaching this unit
Teach prefixes and suffixes by starting with the base word first, then layering the affix to show change. Avoid explaining rules upfront; let students discover patterns through examples and guided questioning. Research shows that students learn affixes best when they physically manipulate parts and discuss their findings, rather than memorizing definitions. Keep examples concrete and tied to familiar actions or emotions to reduce abstraction.
Students will confidently split new words into base parts, explain how prefixes and suffixes change meanings, and create their own words with accuracy. They will justify their reasoning in discussions and apply the rules to unfamiliar words in sentences. By the end of the sessions, they should recognize and use these affixes independently in writing and conversation.
Watch Out for These Misconceptions
During Word Building Stations, watch for students who assume words like 'unhappy' mean the same as 'happy'. Redirect by having partners create two sentences: one using 'happy' and one using 'unhappy', then vote as a class on which fits better in each context.
During the Pair Prediction Game, watch for students who think all prefixes mean 'not'. Ask teams to sort re- words like 'rewrite' and 'rebuild' and explain whether 'again' fits each. Use a class chart to mark re- as 'again' and un- as 'not' for quick reference.
During Whole Class Sort Relay, watch for students who overlook meaning shifts from -ing and -ed. Have teams act out verbs like 'jump' and 'jumped' while others describe the timing of the action on a timeline drawn on the board.
During the Individual Journal Extension, watch for students who treat suffixes as only lengthening words without tense change. Ask them to reread their entries aloud, emphasizing the timing: 'I play' vs. 'I am playing' vs. 'I played', and note the differences in their journals.
