Codebreaker Squad: Spelling & Suffix Lab
Agent Name:
Date:
Master agents decode language patterns with precision! Analyze each spelling rule, apply your code markings, and solve the suffix puzzle blocks below.
Mission 1: Phonogram Rules & Spelling Detectives
Rules: au/aw • -dge/-ge
Rule A: au vs aw /aw/ sound
Use au in the beginning or middle of a base word. Use aw at the end, or before final l, n, k.
1. l n (lawn)
2. c se (cause)
3. str (straw)
4. l nch (launch)
Rule B: -dge vs -ge /j/ sound
Use -dge right after one short vowel. Use -ge after a consonant, long vowel, or vowel team.
1. bri (short i)
2. ca (long a)
3. do (short o)
4. lar (after r)
Rule C: Structured Coding Bench Code symbols: Breve [ ˘ ] • Circumflex [ ˆ ] • Schwa [ ∂ ]
Read each word aloud. Mark the target phonogram using standard RbD coding, then write its sound code (/ĕ/, /â/, or /∂/):
Short ea (/ĕ/) code: ĕa
f e a t h e r sound: [_____]
b r e a d sound: [_____]
Circumflex a (â) code: â
s c a r e sound: [_____]
s t a r e sound: [_____]
Schwa a / o (∂) code: ∂
w a g o n schwa: [_____]
a b o u t schwa: [_____]
Mission 2: Suffix Lab • Adding -ly and -y
Doubling • Dropping • Changing
1-1-1 Doubling Rule
1 syllable + 1 vowel + 1 final consonant + vowel suffix (-y) = DOUBLE final consonant.
Drop Final Silent e
Drop silent e before vowel suffix (-y). Keep e before consonant suffix (-ly)!
Change y to i Rule
If a base ends in a consonant + y, change the y to i before adding -ly.
| Base Word | Suffix | Modified Word (Write Here) | Rule Applied (Circle One) |
|---|
| fog | + y | | |
| 1-1-1 Double • Drop e • Just Add | | | |
| brave | + ly | | |
| Keep e • Drop e • Change y to i |
| bone | + y |
| Drop silent e • Keep e • Double |
| greedy | + ly |
| Change y to i • Keep y • Double |
| chill | + y |
| Just Add (ends in 2 cons) • Double |
| happy | + ly |
| Change y to i • Keep y • Double |
Target Check: Did you verify whether suffix is vowel or consonant before adding?

Part C: Imposter Alert • Spot the Rule Violation
Find the fake spelling
In each pair below, one word follows RbD rules and one is an imposter. Check the legal spelling, write the corrected word, and cite the rule.
Case #1: /aw/ Sound au vs aw
[ ] f a w c e t
[ ] f a u c e t
Correct Spelling:
Why? Use au in middle of word, not aw.
Case #2: /j/ Sound -dge vs -ge
[ ] b r i g e
[ ] b r i d g e
Correct Spelling:
Why? After one short vowel, use -dge.
Case #3: Short /ĕ/ Vowel Short ea
[ ] h e v e y
[ ] h e a v y
Correct Spelling:
Why? Short /ĕ/ in heavy is spelled with vowel team ea.
Case #4: Suffix Doubling 1-1-1 Rule
[ ] s u n y
[ ] s u n n y
Correct Spelling:
Why? 1-1-1 base word before vowel suffix -y must double.
Analysis Check: Look closely at vowel teams vs short vowels before applying rules!

Part A: Decodable Reading Mission • "The Alpine Ridge Dispatch"
Target Decodable Text
At early dawn, Agent Vance stepped onto the stone bridge near the misty gorge. The morning air was chilly, and a light frost covered each wooden ledge. He reached into his coat and carefully gripped a heavy leather case containing the coded dispatch. A solitary hawk circled above the tall pines, watching as he moved swiftly along the narrow path. Vance knew he could not make a single mistake. He glanced down at the muddy tracks, unlocked the bronze latch on the dispatch case, and revealed the golden cipher disk just before sunrise.
