Explanation

About the Math, Learning Targets, and Rigor

This standard calls for students to read and write numbers with a base-ten numerals (number form or standard form), number names (written form), and expanded form (as an addition expression).

Example: 298

Base-ten Numeral: 298

Number Name: two hundred ninety-eight

Expanded form: 200 + 90 + 8

Remember: When reading and writing whole numbers, the word “and” should not be used between any of the whole-number words – “and” represents the decimal point.
