Lesson 5

How random is random?

In this lesson, students will refine their app to ensure that it recommends a unique activity each time a button is clicked. They will examine how random decisions could result in an outcome that does not appear random. They then create a variable to track the previous activity that a user was recommended. Finally, students will use control structures including an if-else conditional and a loop to compare two values and set a new value if they are equal.

CSTA Standards

2-AP-10: Use flowcharts and/or pseudocode to address complex problems as algorithms
2-AP-11: Create clearly named variables that represent different data types and perform operations on their values.
2-AP-13: Decompose problems and subproblems into parts to facilitate the design, implementation, and review of programs
2-CS-01: Recommend improvements to the design of computing devices, based on an analysis of how users interact with the devices.
3-AP-14: Use lists to simplify solutions, generalizing computational problems instead of repeatedly using simple variables.
