:"Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:"
Our Take: Second graders should be expanding their place value knowledge, understanding that 10 tens grouped together is called a “hundred.” Help students learn, for example, that a three-digit number is composed of a ones, tens, and hundreds place. Second graders can illustrate this understanding by identifying the value of each digit in a number, as well as recording that number in the word and standard form.
