Set Notation Using Geogebra
Objective: Students will learn how to read and write set notation and identify common set operations using mathematical notation.
Sets are collections of distinct objects.
Student will use the examples below to practice reading mathematical notation.
Example sets: A = {1, 2, 3, 4, 5} B = {3, 4, 5, 6, 7}
Answers to problems
Question 1 answer: A intersect B is {3, 4, 5}
Question 2 answer: A union B {1, 2, 3, 4, 5, 6, 7}
Question 3 answer: The difference between A - B is {1, 2}
This Applet is an interactive exercise that helps students practice set notation. It uses two examples sets and asks students to find the intersection, union and difference between the sets. The activity helps students become more familiar with common symbols used in discrete mathematics.
This activity can be used in a classroom after students learn the basic of sets. Students can work through the three questions on their own or with a partner and then compare their answers. It is a simple way to practice reading and using set notation before moving on to more challenging problems.
