Geometry deals with shapes and the properties of those shapes. This documents discusses basic concepts of geometry. This e-book will be useful to students taking Geometry in high school and will become handy to those taking the SAT , GRE, GMAT Math section. The topics that are discussed in this e-book are as follows: 1. Polygons 2. Angles 3. Angles Properties in Circles 4. Circles, Chords, Tangents and Quadrilaterals

In this e-document, I will examine basic area concepts that relate to the process of finding the area of a square and rectangle. Manipulation facts are also discussed. Using this document, instructors can have students work in groups and have them find areas of irregular figures that can be portioned into squares and rectangles. The formulas for for finding the finding the areas of squares and rectangles are also given.

What are equivalent fractions? Equivalent fractions are fractions that look different but have exactly the same value. One can generate equivalent fractions by multiplying or dividing the numerator and denominator by the same number. You can simplify fractions by dividing the numerator and denominator by the same number.

At the end of this lesson, the students should be able to subtract numbers by: 1. Lining up the numbers and placing the decimal point appropriately 2. Placing zeros in the placeholders as necessary 3. Subtracting the numbers appropriately Several examples are given. A class exercise accompanied with solutions is also provided.

After teaching Math for many years, I have realized that many students lack the holistic approach to the concept of fractions. Using fractions in Math computations continues to be a challenge to many students in grade school, middle and high schools and even in colleges. Through this book, it is my hope that I can help fill any gaps. Although this E-book is intended for grades 4-6; anyone who needs to understand fractions and how we use them in Math will find it to be insightful. I have starte
