Estimated Time
60 MINS
OBJECTIVES
Identify common prefixes and suffixes in multisyllabic words.
Apply the "Box and Underline" strategy to isolate base words.
Accurately decode words by blending morphemes.
MATERIALS
Prefix Suffix Sleuths Slides
Sleuth Case File (Worksheet)
Highlighters/Colored Pencils
Small magnifying glasses (optional)
The Hook: The Word Tree (10 mins)
Start with the root word "STRUCT" on the board. Explain that roots are like seeds that grow into huge trees when we add branches.
Teacher Script: "Detectives, we have a cold case. This word 'struct' means to build, but it's just a seedling. If we add 're-' to the front, we get 'restructure'. What if we add '-ion' to the end? Help me grow this tree!"
Direct Instruction (15 mins)
1
Define Affixes: Introduce prefixes (front) and suffixes (end) as meaningful chunks.
2
The Box Strategy: Model boxing prefixes/suffixes. Emphasize that isolating them often reveals a simple, 1-2 syllable base word that students already know.
Guided Sleuthing (15 mins)
Use the slides to practice as a class. Call students up to "box" the affixes on the board. Focus on blending the chunks smoothly.

Independent Investigation (20 mins)
Students complete the Sleuth Case File . They must identify affixes, underline base words, and use the word in a sentence to prove they "cracked the code" of its meaning.
Investigation Guide (Answer Key)
Target Word Affixes (Boxes) Base Word (Underline) Disagreement [dis], [-ment] agree Unkindly [un], [-ly] kind Prehistoric [pre], [-ic] history Replacement [re], [-ment] place
COMMON MISCONCEPTIONS
The "Fake Chunk": Students might see a letter combination that looks like an affix but isn't (e.g., the 're' in 'real' is not a prefix). Teach them to check if the remaining part is a real base word.
Spelling Changes: Remind students that when suffixes are added, the base word might drop an 'e' or change 'y' to 'i' (e.g., happiness). This makes the "underlining" slightly trickier!
DIFFERENTIATION
Scaffolding: Provide a "Cheat Sheet" of common affixes with their meanings for students who struggle with memory.
Extension: Have students find "Triple-Affix Words" (e.g., UN-RE-CONSTRUCT-ED) and try to use them in a story.

LESSON FLOW
1. The Gibberish Challenge (Hook): Read a short passage where nouns are replaced with Latin roots. Challenge students to "decode" the context based on root meanings.
2. Root Investigation: Introduce the three target roots. Use the "Case File" slides to model breaking down words like transportation or description .
3. The Root Wall (Activity): Create a classroom wall. Give each pair of students a "Root Brick" (index card). They must find 3 academic words containing that root and present how the root powers the meaning.
4. Lab Report: Independent practice decoding and defining words in a scientific/academic context.
The Detective's Secret
Remind students that Latin roots are often the "stable core" of a word. Even if the pronunciation shifts slightly between words (like describe vs. description ), the spelling of the root usually stays very similar, giving us a massive hint about the word's family.
Lab Results (Answer Key)
WORD ROOT MEANING HYPOTHESIS Supervisor VIS (see) One who sees over or manages others. Inscription SCRIPT (write) Words written into or on something (like a trophy). Importer PORT (carry) One who carries in goods from another country. Vivid VID (see) Clear enough to be seen easily; bright.

THE WORD BRICK CONCEPT
Unlike Lesson 1 (Prefix/Suffix) where there is a clear "base word," Greek combining forms often snap together with equal weight. For example, biology is 50% "life" and 50% "study of."
Teach students to look for the "seam" between the bricks where the words fuse together (often with a connecting vowel like 'o').
Target Forms
BIO- (Life)
GRAPH- (Write)
METER- (Measure)
PHON- (Sound)
Instructional Steps
1
The Invention Connection (Hook)
Show students everyday inventions (telephone, thermometer, telescope). Ask: "If 'tele' means far away, and 'phone' means sound, what is the 'far-away sound' machine?"
2
Modeling the Fusion
Use the slides to show how forms snap together. Use the term "Fusion Vowel" to explain the 'o' often found in the middle (e.g., Bi-O-graphy).
3
The Greek Grid Challenge
Have students build their own "Impossible Inventions" by combining random forms from the Greek Grid worksheet.
Blueprint Key
FUSED WORD COMPONENT 1 COMPONENT 2 MEANING Telegraph Tele (Far) Graph (Write) Writing sent over a long distance. Microphone Micro (Small) Phon (Sound) Device that makes small sounds louder. Photograph Photo (Light) Graph (Draw) Drawing with light. Chronometer Chrono (Time) Meter (Measure) Instrument for measuring time accurately.
Misconception Alert
Students might confuse Greek forms with Latin roots. Remind them that Greek forms are like compound words (LEGO bricks) while Latin roots usually rely more on affixes (person with clothes).
Science Link
Invite the science teacher to collaborate! Students can hunt for these forms in their science lab manuals to see morphology in the "real world."

FINAL RELEASE
CAPSTONE GOALS
In this final lesson, students shift from analyzing isolated words to analyzing words in the "wild." The goal is for them to use morphology as a tool for comprehension of complex informational texts.
Highlight unknown multisyllabic words in a text.
Annotate words using the morphology keys (boxes, roots, notes).
Synthesize meanings to explain the main idea of a complex paragraph.
Field Texts Provided

Investigation Procedure
1
The "Professional Jargon" Hook
Give students a short, dense paragraph from a real medical or legal document. Ask: "Who can read this?" Most won't. Then ask: "Who can find a part they know?" Suddenly, subcutaneous becomes "under-skin" and disability becomes "not-able-state."
2
Guided Annotation
Model how to annotate on the board. Don't just circle the word; write the "translation" in the margin. Show how this helps when reading the next sentence.
3
Final Field Report Activity
Students work independently on the Field Report Worksheet . They must find 5 "Case Words" in the provided text and fully deconstruct them.
Evaluation Criteria
Level 3: Expert
Consistently identifies prefixes, suffixes, and roots. Explanations of word meaning are accurate and connect to the sentence context.
Level 2: Apprentice
Identifies affixes correctly but may struggle with obscure Latin/Greek roots. Definitions are close but lack full context.
Level 1: Novice
Relies on guessing or whole-word recognition. Struggles to break words into constituent morphemes without teacher support.
BEYOND THE CLASSROOM
Encourage students to keep a "Field Notebook" at home for words they see on cereal boxes, street signs, or in TV shows. Morphology is everywhere! For the high-flyers, introduce the concept of Etymology (the history of words) to explain why some words have "monster" spellings.
