Excerpt from Shop Problems in Mathematics
The arrangement is by subjects in order that a student may select those problems in which he is most interested, and that a teacher may readily arrange a course to meet the needs of his particular school. It is suggested that the work of the shop be correlated with that of the mathematical classroom. For example, when a student in a manual training high school is beginning to handle boards in the shop, he is commencing the study of algebra in his mathematical classroom. Let him be assigned some problems in the chapter on Board Measure, together with a review of work in fractions. From these problems he will acquire considerable information that will be useful in the shop, and from the formulas in board measure he will understand the meaning of letters as symbols of general number. If l and t stand for the length and thickness of the board that the student has just sawed off in the shop, they will have a definite meaning to him.
The authors hope that the book will be found useful in any school where there are shops. It is adapted for use in the shop or the mathematical classroom, or in both.
A student of this book should develop an appreciation of the value of mathematics in practical work, since all problems in the book are based on actual shop practice. He should learn to make a formula, solve it for any letter, and apply it intelligently. As he progresses the approximate nature of the results in real problems should become evident. He should learn that real problems very rarely "come out even," - that there is usually an allowance necessary for waste, and he should develop a certain judgment as to what that allowance is.
