See that the pupils can write tenths decimally; as, five tenths (.5), eight tenths (.8), twelve tenths (1.2), twenty-five tenths (2.5), one and four tenths (1.4), two and three tenths (2.3). See that the pupil clearly understands that such expressions as 2.5 may be read in two ways; thus, (a) two and five tenths and (b) twentyfive tenths. 5. 44 × 2, means, 2 times 44; 2 times 44 are 6. .4 × 2, means, 2 times .4; 2 times .4 are 7. 6424, means, find how many times 24 are contained in 64; 24 are contained in 6¢ times. 8. .6 .2, means, find how many times .2 are contained in .6; .2 are contained in .6 times. 9. 642, means, find one half of 64; one half of 6 is cents. 10. .62, means, find one half of .6; one half of .6 is tenths. |
