A self-teaching math worktext for grades 3-4. It includes both the instruction (written directly to the student) and a variety of exercises and word problems in the same book.
This book deals with decimal numbers that have tenths and hundredths—numbers with a maximum of two decimal digits. We only deal with some of the basic operations: addition, subtraction, and multiplication by a whole number, with a strong emphasis on mental calculations. The idea is to lay a solid conceptual foundation so that the student does not succumb to rote memorization of rules and procedures without understanding. Note: multiplication and division of decimals are not covered. Those are taught in Math Mammoth Decimals 2.
