Students also solve problems about arithmetic and geometric sequences based on the numerical data in the wage charts. Lesson 4 Bar Charts, Line Graphs, and Matrices The Soft Drink Company uses bar charts and line graphs to measure the company's progress in three areas of production. The students analyze the pros and cons of the company's data presentation, and develop alternate representations of the data with an accompanying rationale for their choices. Lesson 5 Coded Maps Coded maps include elevation maps, rainfall maps, city recreation maps, etc. In this lesson, students interpret data from a coded map of computer parts and suppliers.
Students create their own coded maps.
Lesson 6 Decision Tree Decision trees are used as a means of problem solving when three or more factors affect the decision. In this lesson, students create decision trees for many topics. Students create a decision tree based on their coded maps from Lesson 5. A comparison between decision trees and flowcharts is made. Lesson 7 Process Control Charts Students simulate computer chip manufacturing by doing an experiment with potato chips.
