Thread 1, Day 3

Agenda

1. Discussion: Four Values
   • Talk through a series of related questions with a small group of your peers, at the whiteboards.
   • Mr. Gordon will circulate to observe, listen, and prompt you as needed.
2. Tutorial: Meet SF Symbols
   • Where your game’s icons come from. Change one, and add one.
3. Tutorial: Your First Playground
   • A place to try a line of Swift and see its value right away.
4. Concept: Variables and Data Types
   • Predict, then run, in your DataTypes playground: what value and type will each line give?
   • Then, in your Guessing Game: a new constant and a new variable.
5. Concept: Making Decisions
   • How does a game choose what to do? Run a buggy medal decision in a Decisions playground.
   • Then, in your Guessing Game: tell the player which way to go.

Things to do before our next class

• If you did not finish the two In your game sections on Variables and Data Types and Making Decisions, or the second change in Meet SF Symbols, finish them, then commit and push.
• Try the practice at the end of Variables and Data Types and Making Decisions. About 15 minutes. Check your answers, and bring questions.
