Pattern Spotting¶

Goal¶

Find and justify which design patterns best fit a real piece of student code — and reflect on how you recognize reusable solution structures in your own work.

Setup¶

Each team gets the design pattern cards from the full design pattern cards deck.
The tutor projects or displays a short code chunk from one of the projects.
Each team uses cards and markers to show their picks.

Play¶

Round 1 — Pick the Pattern Type¶

Observe: Study the displayed code together.
Select: Each team secretly picks the design pattern type they think fits best:
- Creational
- Structural
- Behavioral
Hide & Reveal: Teams place their choice face down on the table (or hand it to the tutor).
Discuss: The tutor flips the cards, compares answers, and leads a short discussion:
- Why that type?
- What signs support your choice?
- What other types were plausible?

Round 2 — Pick the Concrete Pattern¶

Observe Again: Revisit the same code with the chosen pattern type in mind.
Select: Each team secretly picks 1 concrete design pattern card from that type they think applies best.
Hide & Reveal: Teams place their cards face down on the table (or hand them to the tutor).
Discuss: The tutor flips the cards, compares answers, and leads a short discussion:
- Why that pattern?
- What signs support your choice?
- What alternatives might work better?

Scoring¶

Round 1¶

+1 point if two teams suggest the same type.
+1 point if the code’s author team and one other team suggest the same type.
+1 point if at least half of all teams + 1 choose the same type.
+1 point if the tutor’s choice matches your team’s.

Round 2¶

+2 points if two teams suggest the same pattern.
+2 points if the code’s author team and one other team suggest the same pattern.
+2 points if at least half of all teams + 1 choose the same pattern.
+2 points if the tutor’s choice matches your team’s.

Points add up — reasoning and shared insight matter more than luck.
