Day 2 · Reading, Writing & Expanding Large Numbers

347,825 is read as "three hundred forty-seven thousand, eight hundred twenty-five" — in expanded form: 300,000 + 40,000 + 7,000 + 800 + 20 + 5.

900,004 is read as "nine hundred thousand, four" — notice there are no ten-thousands, thousands, hundreds, or tens at all.

Writing a number in expanded form helps us clearly see the place value of each digit.

Activity: Try writing a 6-digit number you see around you, like a city's population, in expanded form.
