In Grade 1, students typically learn to convert words to digits up to 100. This involves understanding the numerical value associated with each word and representing it using the corresponding digits.

Here’s an explanation of how to convert words to digits up to 100:

1. Numbers 1 to 10: The words for numbers from one to ten correspond directly to the digits 1 to 10.

2. Numbers 11 to 19: The words for numbers from eleven to nineteen are unique and do not follow a pattern. For example, “eleven” corresponds to 11, “twelve” corresponds to 12, and so on.

3. Numbers 20 to 100: Starting from twenty, the pattern becomes more regular. The tens place is represented by words like “twenty,” “thirty,” “forty,” and so on. To determine the complete number, you combine the tens place word with the corresponding digit for the ones place. For example, “twenty-one” corresponds to 21, “thirty-five” corresponds to 35, and “ninety-nine” corresponds to 99.

4. Special cases: There are a few special cases to note. The numbers twenty, thirty, forty, fifty, sixty, seventy, eighty, and ninety do not have a hyphen when combined with a digit for the ones place. For example, it’s “twenty-one” (21) but “twenty-two” (22). Additionally, the word “and” is often used to separate the tens and ones places when there is a digit in the ones place. For example, “fifty-two” (52) is spoken as “fifty and two.”

By understanding these rules, students can convert words to digits up to 100. As they progress to higher grades, they will learn how to convert larger numbers using place value concepts and continue building their understanding of numerical representations.
