Why is place value important?
- Place value is important because it helps you understand the meaning of a number. If people just used numbers randomly, no one would know which numbers people meant. You need place value to understand the order of numbers as well. If someone offered you 30 dollars or 99 dollars, you would need to know that 99 is more than 30 if you wanted the greater amount of money.
In the above candy corn image the top number, "34" is represented in standard form.
The middle representation shows each number paired with their place values.
The bottom representation shows the number in expanded form.
Your child can create this diagram on a white board, and write numbers in expanded form from 1-120. This activity, and more, can also be purchased here, on Teachers Pay Teachers.
