Proficient students recognize that given two different digits in a multi-digit number, one digit can represent a multiple of 10 times the digit to its right, and a multiple of 1/10 the digit to its left;
Three-digit numbers can be decomposed in multiple ways (e.g., 524 can be decomposed as 5 hundreds, 2 tens and 4 ones or 4 hundreds, 12 tens, and 4 ones, etc.)
100 can be thought of as a bundle of ten tens-called a “hundred.”
The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
