Flowcharts are a highly visual way of communicating information and are used in this lesson to set up rules about operations that will be performed iteratively. Students are invited to explore what happens when they put different numbers into a given flowchart, and later to experiment with varying the features of the flowchart themselves. They will encounter some converging sequences and use algebra to predict and explain the outcomes.
