SECOND GRADE-SECOND HALF READING AND WRITING TENS AND ONES The figure 0 is called naught or zero. It stands for nothing. When placed to the right of 1, as in 10, the figures stand for ten; when placed to the right of 2, as in 20, the figures stand for twenty; 30 represents thirty; 40, forty; 50, fifty; 60, sixty; 70, seventy; 80, eighty; 90, ninety. The right-hand figure in a number is called ones' figure; the second figure is called tens' figure. Thus, 14 is 1 ten and 4 ones; 21 represents twenty-one. 1. Read: 14 25 48 59 64 70 91 40 2.
