Practical Arithmetics, Book I

This book aims to give the child the ability to compute easily and accurately, and to enable him to interpret and solve the quantitative situations which he will meet in everyday life. Every new operation or detail of a process is presented in connection with an interesting motivating problem that treats of some situation with which the child is familiar. The explanations of new principles and processes have been made as simple and clear as possible. Students are required to take only one new step at a time. Enough exercises are supplied to assure mastery of that step before proceeding to the next one. Checking of computations is taught early in the presentation of each new operation and is required in all exercises.

The pupil's ability in problem solving is developed as systematically as his skill in computation. In teaching two-step problems emphasis is placed upon those types of two-step problems that occur most frequently in everyday life. Most pages contain problems of several kinds, where the pupil must decide whether to add, subtract, multiply, or divide to get the answer. A series of tests on problem solving is also provided throughout the book. These tests cover types of problem situations with which every pupil should be familiar. An important feature of these tests is that they not only measure the pupil's mastery of types of thinking frequently employed in problem solving, but they also check his ability to interpret important language expressions and technical phrases peculiar to arithmetic.

This book provides fully for diagnostic and remedial work. Frequent diagnostic tests are given throughout the book, with keyed references to remedial work. More difficult exercises, marked with a star (*), are provided for advanced students.

In addition to offering ebooks in both Kindle and EPUB format, the Practical Arithmetics, Book I set also includes an 8.5 x 11" printable PDF for each of the four parts so teachers and parents may distribute a hard copy of the text to their students.
