2. Data Types (15 min)

Imagine that you're taking your favorite board game and turning it into a computer-based game.


 Name of board game: Life


 Use the space below to categorize game data into each of the following data types. You should have a minimum of two pieces of data for each category.


String data: player name, car color
Integer and/or float data: number of players, salary, number of kids
Boolean data: college degree, married
Array data: ["Card1", "Card2", "Card3"], [Salary, Bonus, Loans, Tax]
Hash or Object data: score, move count

3. Iteration (30 min)


 On a blank sheet of paper, create a diagram that shows how you understand iteration working. Be detailed and get creative! This should not be the simple table that we used during the lesson. When you're done, take a photo of your diagram and send it to Rachel and Tim on Slack. (If you're feeling extra fancy, feel free to create your diagram using software instead of pencil and paper)


 Create a list below of three real-life situations where iteration is used. For each situation, explain why it would be an example of iteration.


Eating Pie - collect the pie and for each slice, you add whip cream and eat it and then continue on to the next slice


Walking Dogs - you get your dogs and for each dog, you walk for 15 minutes, clean up any mess, and repeat for the next dog


Eating an apple - get your apple and for each apple, you slice 4 times and eat all 8 slices and then repeat for the next apple


 Create a list below of three programming situations where iteration would be used. For each situation, explain why it would be an example of iteration.


Picture editor - collect the pictures and for each image, you can add effects, resize, crop and then the process repeats for the next picture


Health Records - collect patient records and for each patient, confirm appointment and send reminder. Repeat for next patient.


Golf scores - collect golf scores and for each score, find the high score of the day and update other high scores and then repeat with next score
