Additional Notes

This week's material covers basic elements of sets, subsets, set operations, and set notation. Although this material may be covered in a variety of courses prior to college, both the level of coverage and the notation used may vary widely. As a result, some students taking CS 242 may have considerable knowledge of this material, but others may have limited or no experience. Still others may be familiar with the ideas, but utilized different notations. With such variation in backgrounds, the purpose of this week is to bring everyone together with a common understanding of both the concepts and the notation.

As you will see, the reading and participation activities cover sets and related topics in a methodical and detailed manner. However, with varied backgrounds, the amount of time students will need to focus on this material may vary widely.

By allowing students to work through this chapter on their own, students can devote the time they need to achieve the needed mastery.
