As well as the subjects generally included in arithmetic text books, this book also contains simple work in algebraic equations and constructive geometry that was intended to be studied by contemporary elementary school pupils. Containing subject matter intended to be taught in sequence over a period of five months, this text was a definitive handbook for the instructor and contains thirteen chapters including: Numbers of Three Figures; Addition and subtraction; Numbers of Five Figures; Multipliers and Divisors of One Figure; Pint, Quart, and Gallon; Roman Notation; et cetera.
