Age: 8-9 years

Duration: 60 min

Objectives

• Break words into prefix and root parts and define un- (not/opposite) and re- (again).
• Define prefix words in context sentences on worksheets and in oral tasks.
• Build a class prefix word wall with student-generated examples and illustrations.

Vocab

• unhappy / unfair / unpack: un- = not or reverse action.
• rewrite / return / rebuild: re- = again or back.
• prefix / root: "Un- is a prefix added to the root happy."

Warm-up (5min)

Action demo: pack bag → unpack. Say sentence: "I unpack my bag." Ask: "What does un- do?" Repeat with redo, return walk.

Main Activity (45min): "Prefix Word Wall Project"

Word surgery worksheets: split 16 words into prefix + root; define each. Sort cards into un- vs re- columns with sentence proof. Context cloze: fill blanks in short paragraph using prefix word bank. Creative round: invent "school words" (unhomework — discuss humor vs real morphology). Word wall build: each student contributes one un- and one re- word with illustration and sentence on index card. Gallery present: 8 students explain prefix meaning to class. Flyers practice: 8 multiple-choice "Which word means ___ again?" items. Snap quiz exit for data — record scores for G3 mastery tracking.

Wrap-up (5min)

Choral definition: "un- means ___ . re- means ___ ." Point to one word wall favorite.

Teacher Tips

• Spiral Lesson 04 base words — rebuild connects both lessons explicitly.
• un- has two meanings (not / reverse) — teach through examples, not rule list.
• Word wall stays up through Lesson 18 mastery review — refer back often.
