Math Mammoth Grade 7-A worktext is the first part of a complete math curriculum for 7th grade. This is a pre-algebra course, and students can continue to algebra 1 after studying it. The curriculum meets the Common Core Standards for grade 7 but also exceeds them in places (e.g. the inclusion of the Pythagorean Theorem). We start out with an introduction to basic algebra, reviewing the order of operations, the concepts of an expression and equation, and the distributive property. In chapter 2, we study integers and their operations. In the next chapter, students study simple one-step equations. Chapter 4 is titled Rational Numbers. The goal is to be able to add, subtract, multiply, and divide both positive and negative fractions and decimals. The last chapter in part 7-A focuses on linear equations and using those in simple word problems. We also study linear inequalities and graphing. The part 7-B, an answer key book, and a book containing cumulative reviews and chapter tests are available for purchase separately on Lulu.
