To reinforce, ask: How do we write 1? O-n-e. Ask the spelling of random numbers up to 10. Let s observe how to write the next ten numbers in words. Let students repeat the spellings of the above numbers. Ask if they notice any pattern. Explain that though numbers 13 through 19 have teen at the end, the spellings vary, and not all are spelled as the number + teen. It is not three + teen, but thir + teen, or it is not five + teen, but fif + teen.
3 In 18, it is not eight + teen, instead it is eigh + teen (single t ). Students need to learn the spellings. Say and display: Let us learn the spellings for tens. 1 ten = 10 = ten 2 tens = 20 = twenty 3 tens = 30 = thirty 4 tens = 40 = forty 5 tens = 50 = fifty 6 tens = 60 = sixty 7 tens = 70 = seventy 8 tens = 80 = eighty 9 tens = 90 = ninety 10 tens = 100 = hundred Practice the spellings a couple of times. Say and display: To learn to write numbers from 20 to 100, observe the following table.
4 Choose any number between 20 and 100. Example: 58. To write 58, we choose fifty from the first column and eight from the second column and get fifty-eight. We know the spellings of 50 and 8 already. Consider another number, 91. We choose ninety from the first column and one from the second column to get ninety-one. Practice a few more numbers and conclude we can write any number from 20 to100, by just learning the spellings for ones and tens.
