Excerpt from Fourth Book Fifth Year Essential Elements, Vol. 5

This book is for boys and girls who know thoroughly addi tion, subtraction, multiplication, and division, who understand clearly what common fractions and decimals are, who are familiar with counting and comparison, and who can use in simple problems the facts Of weights and measures. For these the new work here includes the multiplication and division Of fractions by fractions and Of decimals by decimals, and further extension and application of the principles Of ratio, proportion, percentage, cancellation, and equation. The rest Of the book consists Of drills and tests in the use Of the fundamental and intermediate principles involved in the theory Of practical arithmetic.

The plan Of this book is to treat a topic and then to review it in connection with problems in preceding topics. One topic after another is taken up with such thoroughness as seems appropriate to the stage Of the pupil's advancement; and some Of the topics are repeated once or twice in the course Of these pages. This plan secures an essentially spiral treatment. Subjects are introduced, but by no means exhausted before we pass to new subjects or to Old subjects displayed in new matter.
