1. Building an App: Multi-Screen App
UNIT 5 – LESSON 3

2. VOCABULARY ALERT:
Event-driven program - a program designed to run blocks of code or functions in response to specified events (e.g. a mouse click)
Event handling - an overarching term for the coding tasks involved in making a program respond to events by triggering functions.

3. PURPOSE: Reinforce programming skills in App Lab while quickly prototyping a simple event-driven application. The lesson does, however, fall at the intersection of the Big Ideas of Creativity and Programming. The fact that you will share ideas before programming your projects and will provide feedback using a peer rubric also mirrors some of the practices of collaboration that you can employ on the Create Performance Task.

4. Today you will get a chance to make an app of your own design that uses multiple screens and lets you practice using design mode and programming some simple user interactions. We want to spend most of our time working on it, so let’s get to it.

5. You need a partner. Each person will make his/her own project, but run ideas past your “programming buddy”.

6. Interesting note: if you want to play or stop music, this is what you need.

7. Follow the instructions in Code Studio and on the Activity Guide Distribute: Activity Guide - Multi-screen App - Activity Guide

9. HOMEWORK: Finish your app to show in class
HOMEWORK: Finish your app to show in class. You can take a couple of days, but it is due before break!
