The purpose of this lesson is to present a unique and fun method to introduce the concept of angle recognition and identification to students who are Deaf and/or Hearing Impaired as well as other students included in special education.
The game "Teeing for Angle" ©1999, was formulated to enhance the lesson presentation on Angles. Upon completion of each given assignment, the students would engage in this wonderful activity which encouraged team work, competitiveness, development of self esteem, and increased eagerness to acquire knowledge about angles and the many ways they are used in our daily lives..
TITLE: TEEING FOR ANGLES
GRADE LEVEL: 9 - 12 (AS WELL AS ELEMENTARY GRADES)
When the class is beginning the lesson on angles, the students will receive 25 index cards, cardboard strips which have information about the angles (names, shapes) for example, _______ is a straight angle and a 0 is a circle. The students will copy and/or draw each angle on the index cards,: drawing the angle on the front of the card and writing the definition or identifying information on the back of the card. The students will also be given small writing tablets to record any additional information about specific angles that they read about or discuss during class.
The students will also be expected to describe the various types of lines ( parallel lines, line segments, and the point) as well as comprehend the use of triangles when drawing varied angles. The angles drawn on the chalkboard may, upon connection form right triangles, scalene triangles, acute triangles, etc. The student will see the difference in the angles used to compose these triangles as well as see the use of angles in other areas.
|90 degree angle||45 degree angle|
(to show that this is not an angle)
|Right Triangle||Acute angle|
The sum of the measures in degrees of the three angles of a triangle is 180o This information can be used to determine the sum of the of the measures of the angles of a polygon with any number of sides (without measurement). For each polygon that follows, draw all diagonals from vertex A. Assume all polygons to be regular (all sides with the same length and all angles congruent
1. Complete the following table:
| Angle Sum
| Angle Sum
STATE A RELATIONSHIP BETWEEN THE NUMBER OF SIDES OF ANY GIVEN POLYGON AND THE NUMBER OF DIAGONALS THAT CAN BE DRAWN FROM ONE VERTEX
STATE A RELATIONSHIP BETWEEN THE NUMBER OF SIDES OF A POLYGON AND THE NUMBER OF TRIANGLES FORMED BY THE SIDES AND BY THE DIAGONALS FROM ONE VERTEX
WHAT IS THE SUM OF THE MEASURES OF THE THREE ANGLES OF ONE TRIANGLE?
WHAT IS THE SUM OF THE MEASURES OF THE INTERIOR ANGLES OF A POLYGON OF 'N' SIDES?
2. IN THE ILLUSTRATION BELOW, LINE AB IS PARALLEL TO LINE CD.
THE GAME: TEE FOR ANGLES
THE PURPOSE OF THIS GAME IS TO ENHANCE LEARNING AND COMPREHENSION OF THE USE OF ANGLES IN EVERYDAY LIFE FOR STUDENTS OF ALL AGES. A COPYRIGHT FOR THIS GAME WAS OBTAINED IN FEBRUARY, 2000 AND I AM IN THE PROCESS OF HAVING IT PATENTED AS A BOARD GAME.

IF YOU LOOK CAREFULLY, YOU CAN SEE THE DOTS ON THE PICTURE ABOVE.
- THE GAME CONTINUES UNTIL ONE STUDENT HAS FORMED MORE ANGLES THAN ALL THE OTHERS
- THAT STUDENT RECEIVES THE PRIZE
- IN THE CASE OF A TIE, THE STUDENTS WILL HIT THE BALL AGAIN.
- THE STUDENT WHO MAKES THE FINAL ANGLE IS THE WINNER.
