Teaching Vocational Mathematics.
Thiering, Jeannette; And Others
This Australian document is a guide to teaching mathematics as it relates to specific work situations. After a brief introduction, chapter 1 looks at problem solving, advises teachers to lower the reading level and thus raise the understandability of written math problems, and describes a four-step problem-solving process. Chapter 2 outlines a lesson that teaches a math concept and provides other examples of using concrete aids. Chapter 3 discusses teaching estimation by using number skills, mathematical common sense, and concepts of size. The chapter also includes brief sections on practices in the trades regarding rounding numbers up and down. Chapter 4 covers formulas, including the terminology of formulas, their place in school mathematics, and how formulas are taught in vocational courses. Chapter 5 covers decimals, including the following: (1) the meaning of decimal notation; (2) the use of zero in decimals; (3) essential zeros; (4) the order of size in decimals; (5) rounding; (6) multiplying and dividing by 10, 100, and 1,000; and (7) multiplication and division by numbers smaller than 1. Chapter 6 covers common fraction ideas, equivalent fractions, and simplifying fractions. Chapter 7 deals with percentages by examining the following: (1) common percentage ideas; (2) comparing two quantities as a percentage; (3) decimals and percentages; (4) finding a percentage of a quantity; and (5) working out 100 percent when given another percentage. Chapter 8 offers worked examples of math problems relating to fitting and machining, plumbing or building, automotive engineering, and commercial cookery. Several chapters include student worksheets reinforcing the chapter concepts and information. (CML)
