Common Mistakes

MISTAKE: Confusing the 'tens' digit with the 'ones' digit, e.g., thinking 58 is eight tens and five ones. | CORRECTION: Remember the digit on the left (5) is the tens place, and the digit on the right (8) is the ones place.

MISTAKE: Reading 58 as 'five and eight' instead of 'fifty-eight'. | CORRECTION: Practice reading two-digit numbers correctly. The '5' in 58 represents fifty, not just five.
