Place value is all about understanding how much each digit in a number is worth based on its position. In third grade, we usually work with numbers up to the thousands place. For example, in the number 3,452, the '3' is in the thousands place, so it represents 3,000. The '4' is in the hundreds place, representing 400, the '5' is in the tens place, representing 50, and the '2' is in the ones place, representing 2. Understanding place value helps us add, subtract, and compare numbers!
Let's break it down further: the value of a digit increases tenfold as it moves one position to the left. So, understanding these concepts is key!
