Activity Guide - Conditionals Make

Step 1 - Try the app

Try making tickets for different combinations of inputs.

Make a ticket for a weekend.
Make a ticket for a weekday (Monday - Friday) and someone 18 or younger.
Try the discount code "FREEFRIDAY" on a Friday.

Discuss with a Partner

What variables would you need to program this app?
Where does this app use conditionals (if-statements)?

Step 2 - Plan

Variables: Fill in the table below for each variable you'll need to create.

Variable Name	What the Variable Stores
age	Age of the person
day	Day of the week
discountCode	Stores the discount code

Conditionals: Draw a flowchart that follows the rules below. There's more than one way to do it. Use the table to make sure that your flowchart works for different combinations of age, day, and discount code.

On the weekends ("Saturday" and "Sunday") everyone pays full price of $10
On weekdays (Monday through Friday) if you are 18 years or younger you pay $5.
If you use the discount code "FREEFRIDAY" on a Friday you get in for $0. No other discount codes will work and the code only works on Fridays.

Age	Day	Discount Code	Price
18	Monday	none	$5
18	Saturday	none	$10
50	Monday	none	$10
50	Saturday	none	$10
18	Tuesday	FREEFRIDAY	$5
50	Friday	FREEFRIDAY	$0
18	Friday	FREE	$5
50	Friday	FREE	$10

Step 3 - Write Your Code

Write the code for the app, using your plan above and the comments provided in Code Studio to help
Step You Can Follow

Create all the variables from your table above.
Give your variables a starting value using the assignment operator (=)
Create an event handler (onEvent) for the "calculate_button"
Inside the event handler start writing code for your conditional using your flowchart
Test your code as you go using the table below. At the end it should work for every combination of outputs in the table on the first page.
Use your debugging skills to identify unexpected behavior and fix your program
Comment your code as you go, explaining what each event handler does

Check the Help & Tips tab for ideas about Programming Patterns you can use
Extension Ideas

Add another discount code for a different day of the week or age range
Make guests 65 and older always pay $5 unless they use a discount code

Step 4 - Submit

Before your submit check the rubric below to make sure your program

Category	Extensive Evidence	Convincing Evidence	Limited Evidence	No Evidence
Input	onEvents are created for all the required inputs.	onEvents are created for most of the inputs.	onEvents are created for some of the inputs.	onEvents are not created for any inputs.
Storage: Variables	Variables are created and appropriately used for all pieces of information used in the app.	Most information is stored in a variable and appropriately updated throughout the app.	Some information is stored in a variable and appropriately updated throughout the app.	There are no variables which store the necessary information for the app to work correctly.
Processing: Conditional Logic	The code correctly determines the price for all combinations of inputs (age, price, discount code).	The code correctly determines the price for most but not all combinations of inputs (age, price, discount code).	The code correctly determines the price for some but not all combinations of inputs (age, price, discount code).	The code does not correctly determine the price for any combination of inputs (age, price, discount code).
Code: Output	The screen correctly displays the day, age, and price of the ticket.	The screen displays most but not all information correctly in the ticket.	The screen displays some but not all information correctly in the ticket.	The screen does not correctly display any information in the ticket.
Code runs without errors.	No errors are present in the required code.	On or two errors are present in the required code.	Three or four errors are present in the required code.	More than four errors are present in the required code.
Coding Comments	Comments are used to correctly explain the purpose and function of all onEvents and conditional logic.	Comments are used to explain the purpose and function of most onEvents and conditional logic.	Comments are used to explain the purpose and function of some onEvents and conditional logic.	Comments are not present.
