SNACK HEIST MYSTERY • 8TH GRADE ORAL DISCOURSE
WIDA 2.8 Target Scaffold
Student Profile Analysis (WIDA Speaking 2.8 / Composite 3.8-4.0) Dyad Dynamics: 2 Apprehensive Speakers
The Receptive vs. Productive Gap: These students understand rich grade-level academic English (Composite ~4.0), but performance anxiety and lack of procedural automated sentence frames inhibit oral output (Speaking 2.8). In pairs, both can default to silent agreement or pointing.
The Pedagogical Solution: An Information Gap structure. Because each student holds mutually exclusive clues that are hidden from the other, oral communication is not performative—it is a functional necessity to solve the game.

Essential Dyad Speaking Norms (Reinforce Constantly)
1. Eyes on Partner, Not Page: Students read their clue silently first, then look up to speak it aloud to their partner.
2. Mandatory Clarification: Listener must say: "Can you repeat that?" or "Who was at...?" before writing.
3. Equal Airtime Rule: Neither student may make an accusation until both have shared two clues each.
