Number Names
In 1st grade, you have studied number names up to 20. Now here you will learn names of the larger number. You have already learned the number-names from 1 to 20 and also number-names of 30,40,50,60,70,80,90 and 100. Here we will use the number-names of these numbers.
Example 1: Write the 128 in words.
Solution :
First write the given number in expanded form and write the name of each number below it and then combine that name.
128 = 100 + 20 + 8
= One Hundred + Twenty + Eight
So the number-name of 128 is
one hundred twenty eight.

Some times we have number-names and from that we have to write the number.
Example 1: Write in numeral of Two hundred twenty four.
Solution:
First write the number-name, below that write each numeral and then combine them together. For making it easy I am giving plus sign between each number.
Two hundred + twenty + four
200 + 20 + 4
= 224

Example 2: Write in numeral of Three hundred fifty six.
