An algebra book written by a math major who taught math in high school. If you need a solid introduction to algebra with the use of modeling, this book is made for you. Many algebra texbooks now use modeling to explain algebra because it helps students to quickly understand complicated concepts easily. The first 3 lessons cover integers. Why 3 lessons? Most students struggle with integers. Without a mastery of integers, everything else falls apart. These 3 lessons will ensure a mastery of the topic and a smooth transition to more complicated concepts. Then, lessons about solving equations make use of modeling with colored rectangles and squares. If you are a novice with modeling, be assured that it is easy to learn. Things will get interesting once you start modeling equations with fractions. Finally, the lessons about exponent, roots, scientific notation, and the Pythagorean Theorem are short, but carefully worded. Units are closed up with a summary and key exercises. The summary provides you with the gist of the unit and the key exercises provide more practice, additional challenge, and a way for you to test if the unit is mastered. A final test that will measure every skill taught in the book.
