Warm-up (5min)

Show helpful vs helpless pictures — students define using full of / without frame. Add one sentence each.

Main Activity (45min): "Suffix Meaning Lab"

Word build cards: base + -ful or -less — create 12 words, define, sketch. Pair challenge: same base, both suffixes — "hopeful vs hopeless" paragraph compare. Context reading: short story with 8 suffix words — highlight and margin-define. Sentence creation: each student writes 4 original sentences (2 -ful, 2 -less) about school life. Suffix sort race: teams classify 20 words — debrief tricky ones (fearless vs fearful preview). Connect to word wall from Lesson 08 — add suffix column. Flyers vocab quiz: 6 items choose opposite suffix meaning.

Choral frame: "-ful means full of ___. -less means without ___." One new sentence aloud.

Teacher Tips

• Completes G3 morphology arc: roots (L01, L04), prefixes (L08), suffixes (L15).
• hopeless looks like hope + less — confirm meaning with sentence, not spelling alone.
• careful/careless pair is excellent for discussing opposite suffix effects.
