Worked Example
Step-by-Step
Let's say a school has 100 students in Class 1. --- On the first day of the new term, one new student joins Class 1. --- To find the total number of students, we add the new student to the existing students. --- So, 100 students + 1 new student = 101 students. --- The total number of students in Class 1 is now One Hundred One.

Common Mistakes
MISTAKE: Writing '1001' instead of '101' when hearing 'One Hundred One'. | CORRECTION: Remember that 'One Hundred One' means 1 hundred, 0 tens, and 1 unit. '1001' is 'One Thousand One'.
MISTAKE: Confusing 'One Hundred One' with 'One Hundred Ten'. | CORRECTION: 'One Hundred One' is 101. 'One Hundred Ten' is 110. Pay attention to the 'tens' place value.
MISTAKE: Thinking '101' is the same as '11'. | CORRECTION: '11' is 'Eleven'. '101' is 'One Hundred One'. The extra '0' in the tens place makes a big difference in value.
