If, within the time limit, you fail to get the correct answers to all of the problems in a test, practice solving the problems of the same kind on pages 272-275, then try the test again. Test No. 11. Divide. Time limit, 5 minutes. If you had no trouble with the test above, try to get the correct answers to these problems: *1. 9768 X 798 = ? *2. 1,398,061 162 = ? While a class as a whole is working on the Fractional Part in Chapter II, those pupils who are below the standards on the tests above should be given extra time daily for practice, using the exercises on pages 272–275. This exercise and the others like it through the book are to help you measure your progress in computing. Try, within a limit of 12 minutes, to make a score of 100 points. The number of points to be counted for each correct answer is given in parenthesis below the letter of the problem. CHAPTER II. THE FRACTIONAL PART 17. Some Uses for the Fractional Part1 [Without pencil.] 1. In order to get the dimensions of the patterns on page 31, first study this ruler: יזיזייזיויזיג Find on the ruler: 1 inch, inch, 1 inches, inch, 11 inches, of an inch, 13 inches. 2. What sign is used for inches? 3. Point out on the ruler: ", 5", 18", 18", 27". 13. The dimensions of the patterns on the next page are given in inches. Find the length and the width of the material required for each article. Such parts of a quantity as one half (), one fourth (1), three fourths (2), one eighth (1), and five eighths (3) are called fractions. 14. Name the fractions used with the whole numbers on the pattern for the tray. Name those used on the pattern for the portfolio. 1 The purpose of the first half of this chapter is to review former work in fractions and to lay a foundation for the technical treatment that comes later. |
