Thread 1, Day 3

Agenda

1. Concept: Binary Numbers
   • Read this mini-lesson to get a very brief introduction to how computers store numeric data.
2. Tutorial: Xcode Playgrounds
   • Please follow the steps described in this tutorial to create a playground named Data Types and Structures.
3. Concept: Data Types
   • Use the playground you just created to try out the examples given in this mini-lesson.
   • Take notes in your black hardcover notebook, or in your portfolio entry for today in Notion.
4. Concept: Structures
   • Try out the examples described in this mini-lesson in the same playground you already have open.
5. Exercise: Model Hockey Cards Data Using Structures
   • Here is a close-up of a retro-style hockey card for an imaginary player.
   • Here is an image of several similar cards.
   • Write structure(s) in your playground to describe the data shown in the hockey cards.
   • Then create instances of your structure for at least three hockey cards.

Things to do before our next class

• Complete the exercise on structures as described above, then write about what you learned in a portfolio entry on Notion.
