Unit 4: Day 2
Tasks
This lesson has been designed with flexibility in mind. You can:
- Give catch up time
- Introduce concepts from the Theory Unit.
- Etc...
41.1 Ex3 - Music Festival Registration
- Uses window.prompt which students may not have been exposed to before. Explain that these pop up windows override the rest of the code until they are finished.
- That is why I left Draw blank and used the mousePressed function. BUT draw is still needed to keep the program running.
- Therefore, window.prompt boxes are to be used sparingly. Instead, we will rely mostly on single key presses and more complex uses of the mouse.

// print("Debug: testing name variable: " + name);
year = window.prompt("What year were you born?");

41.1 Boolean Quick Check #1
- I have developed a series of Google Form Quizzes to act as formative assessments. They get successively harder as the examples progress.
- A copy can be found in the Resources folder 1.4 - Year 1: Programming Part 2
- Or you can see a student version of the quiz here.
- Have each student write down the variables at the top of the quiz on scrap paper before they begin so they do not need to scroll up and down.
