Title of Book: Angles Are Easy as Pie

Author: Robert Froman

Publisher: Thomas Y. Crowell Company

ISBN: 0-690-00916-X

Grade Levels for Recommended Use: 4th-6th

4th Grade: (6) Geometry and measurement. The student applies mathematical process standards to analyze geometric attributes in order to develop generalizations about their properties. The student is expected to: (C) apply knowledge of right angles to identify acute, right, and obtuse triangles; and (7) Geometry and measurement. The student applies mathematical process standards to solve problems involving angles less than or equal to 180 degrees. The student is expected to:(A) illustrate the measure of an angle as the part of a circle whose center is at the vertex of the angle that is "cut out" by the rays of the angle. Angle measures are limited to whole numbers; (C) determine the approximate measures of angles in degrees to the nearest whole number using a protractor

Brief Summary:

Angles Are Easy as Pie, offers readers to learn about angles and explains in detail of angles in shapes and how they are in our everyday lives. Froman explains angles on a circle, a pie and clock, various shapes and explains various numbered angled shapes from a triangle to an octagon.

Materials needed:

internet, projector, speakers, book, protractors, circle (one for each student), pencils

Suggested Activity:

1) Read parts of the book to the class. Show class the angle pieces of a triangle which will make a straight angle which is 180 degrees. (Class activity) 2) Play YouTube Song Video while passing out circles and protractors. http://www.youtube.com/watch?v=2MWYakuD8_k

3) Hands on Activity: Practice by requiring the student to have 4 angles labeled on a given circle (straight, obtuse, right, and acute angles) as well as the degree of the given angle. Play YouTube video in background during activity. http://www.youtube.com/watch?v=vB9Fax-9nAs Make sure that the students understand how to use the protractors and understand the activity.
