A self-teaching math worktext for grades 5-6. It includes both the instruction (written directly to the student) and a variety of exercises and word problems in the same book.
The main topics of this book are mental math strategies, simple equations and expressions, the order of operations, partial products, using all four operations in solving problems, and number patterns in the coordinate grid. Although the book is named “The Four Operations,” the idea is not to practice each of the four operations separately, but rather to see how they are used together in solving problems and in simple equations. This is to develop algebraic thinking, including the abilities to: translate problems into mathematical operations, comprehend the many operations needed to yield an answer to a problem, “undo” operations, and so on.
