# Venn-Diagram

Introduction This lesson is designed to introduce students to the idea of a set with Venn-Diagram. In this Lesson, Students will experiment with sets in conjunction with the Venn Diagram. Objectives Upon completion of this lesson, students will: understand the notion of sets in Venn diagrams. learn the terminology used with sets and Venn diagrams. practice the placement of set notion in a Venn Diagram. Activities Open the link in order to demonstrate this activity to the students. Begin to explain the applet to the students by showing them the first example on the page. Ask the class if they know what the answer is. When a student has responded correctly, show the class that by clicking in the appropriate section of the diagram, the circles representing the sets. Show the students the location of the "Check Answer" button and check the students' answer together. Guided Practice Let students to try another example, letting the students direct your moves. Or, you may simply ask, "Can anyone describe the answer?"

## Independent Practice

Allow the students to work on their own and to complete some homework.
