Creating Functions
Quit repeating yourself ... you can make this simpler! Rather than repeating the same set of code over and over, class members learn to build and call functions in a series of challenges in App Lab. In the end, they combine functions to...

The Need for Algorithms
Pairs work through two scenarios that require them to generate an algorithm. The first activity requires pairs to define a common language to use; the second comes with the language. The pairs then must determine how to code the...
