One of the skills associated with place value is to be able to work with numbers in different forms:
“Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form.” CCSSM 4.NBT 2
Using base-ten numerals is what we often refer to as standard form. Using number names is word form, and expanded form shows the value of each digit. Here’s an example:
Standard form: 207,485
Word form: two hundred seven thousand, four hundred eighty-five
Expanded form: 200,000 + 7,000 + 400 + 80 + 5

When you think about it, we rarely write a number using words. Can you think of one activity that does call for word form? Yep, that’s correct, writing checks. Give your kiddos some real-world experience by having them write checks! My third-grade teachers are going to cut pictures from catalogs, place them around the room, and let the kiddos shop and write checks for their purchases. What an engaging idea!
