Common Mistakes
MISTAKE: Confusing 'nineteen' with 'ninety'. | CORRECTION: Nineteen is 19, a small number. Ninety is 90, a much larger number. Listen carefully to the 'teen' or 'ty' sound.
MISTAKE: Writing '109' when asked to write nineteen. | CORRECTION: Nineteen is '19'. '109' is one hundred and nine. Remember, 'nineteen' only has two digits.
MISTAKE: Thinking nineteen is an even number. | CORRECTION: Nineteen is an odd number because it cannot be divided exactly by 2. Even numbers always end in 0, 2, 4, 6, or 8.
