Today the students worked on making a calculator in XCode. They reinforced some topics that they had learned in previous classes, such as data types. They had to add buttons onto the calculator, and then adjust the code to work for other operations, like addition or subtraction. Then, they went over if statements and learned about loops. After break, the students worked on a program that put powers onto numbers and got the result. Then, the students learned about mutable and immutable arrays. The used this knowledge to make an animation with two images that looped over and over again. They added more images to their program, and then wrote their reflections.
