A high-energy 50-minute 5th grade decoding lesson focused on dissecting 3-syllable words featuring vowel teams and common inflectional suffixes (-ing, -ed, -er, -est, -s). Students learn a systematic codebreaking protocol to isolate suffixes, detect vowel teams, divide syllables, and accurately blend complex multisyllabic words.
Out of all the runner drones, Falcon-9 proved to be the
in the race.

FACILITATION GUIDE
Key Morphological Insight: When Does Suffix -ED Add a Syllable?
Fifth graders frequently over-syllabicate the past tense suffix -ed. Remind students of the Base Ending Rule:
1. Adds an extra syllable (/id/): ONLY when base ends in /t/ or /d/ (e.g., re-peat → re-peat-ed [3 syll], load → un-load-ed [3 syll]).
2. Does NOT add a syllable (/t/ or /d/): When base ends in other consonants (e.g., soak → soaked [/t/, 1 syll]; screamed [/d/, 1 syll]). In this lesson, our target -ed words always have base /t/ or /d/ to make 3 distinct syllables!
Tiered Support & Scaffolding Strategies
Support (Tier 2 / Striving)
Provide physical highlighter tape to physically mask the suffix before reading base.
Use dry-erase syllable cards where prefix, vowel team root, and suffix are distinct colors.
Reduce load: complete odd-numbered items only, focusing on vocal blending.
Encourage self-correction by asking: "Does that sound like a real word in your vocabulary?"
Pair students during context sentence check to articulate how suffix altered word function.
Target: Full packet mastery
Extend (Tier 3 / Advanced)
Challenge students to add prefix changes: explain → un-ex-plain-a-ble.
Syntax Challenge: Write original sentences shifting from verb (-ing) to noun (-er).

Teacher Correction Scripts (If You Hear... Then Say...)
Error: Student splits vowel team (e.g., reads re-peat-ed as re-pe-at-ed).
Correction: "Look at those two vowels: E and A are sitting together. What is our golden rule? Vowel teams stick together as ONE sound! What sound does EA make here? /ē/. Now blend: peat!"
Error: Student tries to divide the word from left to right without boxing the suffix first.
Correction: "Stop the clock, Agent! Step 1 of our decoder algorithm is ALWAYS Box the Suffix. Remove the ending first so the base word becomes simple and clear!"
