Publisher: Thomas Y. Crowell Company
ISBN: 0-690-00916-X
Grade Levels for Recommended Use: 4th-6th
TEKS
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.

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.
