Gaining Skill with Arithmetic
This hardcover textbook has 170 lessons, counting tests. Lesson concepts are explained in the student text. The book reviews and extends concepts taught in the previous grades. Reading problems are exercised regularly, and the following areas of study are also covered.
Numbers—Place value to hundred billion, decimals to thousandths, factoring and prime numbers. Measures—Metric system: basic units and prefixes, changing units. Fractions—Multiplying and dividing, understanding ratio and proportion. Geometry—Finding volume, introduction to lines, points, and angles. Percents—Fraction-decimal-percent equivalents.

The 17 chapter tests are bound in a separate booklet with tear-out sheets.
The teacher’s manual comes in two volumes. Each lesson shows the pupil’s pages full size with answers filled in. Extra pages give detailed guidance for the teacher in lesson presentation. Answer keys for speed drills and tests are included.
