A Geometry Chapter
Mathematics textbooks are imperative to students’ survival in a math class. Their importance centers on enhancing students’ learning potential, defining the curriculum for that class/grade, and establishing instructional guidelines that lead teachers and students to the content goals or standards of the subject (Lester & Cheek, 1997). Every chapter in a math textbook highlights the different concepts and strategies that students need to successfully master in order to fully understand the material, pass their exams, and thrive in the classroom. In the first chapter of the geometry textbook discussed in the previous inquiry paper, the main strategies or concepts discussed are identifying points, lines, and segments, using the midpoint and distance formulas, measuring angles and understanding their relationships, classifying polygons and finding the perimeter, circumference and area. Although the use of this textbook is important, teachers and students can benefit a great deal from incorporating additional texts that will supplement the material in a fun and interactive way. Some examples of additional literacy texts are wikis, images, video, internet inquiries, etc (Vacca, Vacca & Mraz, 2011). These examples, along with many other literacy texts act as motivational tools that act like a “spoonful of sugar to help the print go down” (Vacca et al., 2011). In this paper, we will discuss some of these supplemental literacy tools that can be used for the first chapter of the geometry book in my observation classroom.
Additional Text # 1
One important text to supplement this chapter is called Sir Cumference and the Great Knight of Angleland (2001). This book is part of a geometry series children’s books geared towards 4th grade and up. The stories focus on a family of three, the father Sir Cumference, the mother Lady Di of Ameter, and their son Radius. In this specific book, Radius longs to be a knight so he travels on a quest to save the King of Angleland. Before he leaves, Radius’s mother gives him a perfect circle medallion that severs as a protractor with degrees on it. As he trains for this quest, Radius learns about 90º angles, 180º angles and other types of angles that will help lead him through his journey and battles. I chose this text because it is a quirky story that will interest students as well as teach them about the different types of angles and how to measure or classify them. Although the level of the book might not suit high school students, I still believe they will benefit from it. The images and stories will lead studnets to understand and remember the material easily. In addition to this text, there are other books in the series that can be used to strengthen students’ geometry skills using other interesting stories.

In addition to the above text, one very important type of text comes from media sources such as Mathematica. An example of this is the Angle and Length Measurement of...
