What is the standard form in math for 3rd graders?

For 3rd graders, "standard form" in math means writing a number using only digits (numerals), like 4,521, which contrasts with word form (four thousand, five hundred twenty-one) and expanded form (4000 + 500 + 20 + 1). It's the normal way we write numbers to show their value in each place (ones, tens, hundreds, thousands).
