Angles Lesson Plan

---

Abstract

This lesson allows students to learn different types of angles including:

adjacent alternate exterior alternate interior verticle

acute obtuse right

Standards (NCTM 3-5)

Geometry

Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships

• identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes;

Specify locations and describe spatial relationships using coordinate geometry and other representational systems

• describe location and movement using common language and geometric vocabulary;

Student Prerequisites

• Technological:
  
  Students must be able to:
  • perform basic mouse manipulations such as point, click and drag.
  • use a browser such as Netscape for experimenting with the activities.

Teacher Preparation

Students will need:

• access to a browser.
• access to pencil and paper.

Lesson Outline

1. Focus and Review
Review all information previously covered on angles.


2. Objectives
Students will identify different types of angles including:



adjacent alternate exterior alternate interior verticle

acute obtuse right

3. Teacher Input
Explain the rules to the What's Your Angle? game.
4. Guided Practice
Have the students play the What's Your Angle? game.
5. Independant Practice
• Tell the students to open the Angles Applet.
• Have the students complete at least 10 computer generated problems from the Angles Applet.
• Instruct the students to copy down the angles given to them by the computer along with the correct answer to the computer generated questions.

6. Closure
Review the different types of angles by having the students come to the front of the class and point out the different angles on the floor angle model.
