Directive: The central mainframe has been locked by a rogue cyber-virus. To restore system power, decode the scrambled syllable data-packets below. Match the syllable segments, identify their division rules, and transfer your decoded passcodes to the Decryption Terminal on Page 2.
RULE 1: VC / CV
Split between two consonants in the middle. (e.g., mag / net)
RULE 2: AFFIX STRIP
Peel off known prefixes & suffixes first. (e.g., dis / rupt)
RULE 3: V / CV
One consonant? Try splitting before it. (e.g., ro / bot)

Phase 2: Master Security Passphrase
Extract the target letter from each word you decoded above to uncover the 6-letter security key.
• Letter 1 = 3rd letter of your decoded word in #A1
• Letter 2 = 4th letter of your decoded word in #A2
• Letter 3 = 1st letter of your decoded word in #A6
• Letter 4 = 4th letter of your decoded word in #A4
• Letter 5 = 5th letter of your decoded word in #A5
• Letter 6 = 4th letter of your decoded word in #A3

Part 4: Field Intel • Decode in Context
The defense team attempted to establish a new firewall before the cyber-bug could disrupt the main network. A magnetic lock kept the server door secure while agents verified that every unauthorized code had been completely suspended.
Q1. What did the defense team attempt to build/set up to stop the bug?
Q2. In the text, which decoded word means "to pause or hold back"?

Self-Contained ELA Facilitator Routine: Syllable Division Protocol
1. Tactile "Finger-Slash" Method:
Have students place their index fingers on the two vowel letters. Ask: "How many consonants are caught between your fingers?" If two consonants, have them make a physical chopping motion between them.
2. Verbal Prompting Script:
If a student freezes on a 3-syllable word, cue: "Cover everything except the first chunk. Sound that out. Now slide to the middle chunk. Now punch the last chunk together!"

IEP Accommodations & Error Correction Matrix
Motor Accommodations
Allow students who struggle with handwriting to place pre-cut syllable cards or use colored highlighter tape instead of writing pencil slashes.
Common Misconception
Students often count vowel letters rather than vowel sounds (e.g., counting silent -e). Remind students to listen for the vocal beat.
Differentiated Extension
Challenge fast finishers to invent their own 3-syllable security password, chunk it with slashes, and trade with a partner to decode.
