Whole number place values up to millions

In this lesson, we will learn:

• The names and values of place values to the millions
• How to write large whole numbers up to millions in standard form, expanded form, and written form

Notes:

• Place value names can be memorized by looking at the pattern of every three place values

• The standard form of large whole numbers should have commas (,) or spaces between every three place values (every 3 digits, starting from the ones place)
• Ex. 43528796 should be written as: 43 528 796 OR 43,528,796 for clarity
• The value of each digit of each place value is related to powers of 10:

• Ex. 126 in expanded form is:

• The written form of a number uses words to name the whole number
• Name each group of 3 digits, then write the name of the group ("million" or "thousand")
• Ex. 143,528,796 in written form is:
