Students began the afternoon by reviewing the custom button project they worked on the day before. They built off of the topics they had already learned and continued working with the button to add a label and make it transparent so that the rectangle would still change colors when clicked.
Once this was achieved, Rob began explaining the next project for the students. The class spilt into several groups of two to build their own apps. Rob drew a template on the board for them to construct on the computer. The purpose of this app was to build a prime number finder so that students could easily identify prime numbers in a range that they chose. After they had everything connected, Rob ended the class by explaining how to build a function to find prime numbers so that they could implement this into the application the following day.
