MD.MA.2.NBT. Number and Operations in Base Ten (NBT)
2.NBT.A. Understand place value.
2.NBT.A.1a. Major Standard: 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 a special case: 100 can be thought of as a bundle of ten tens–called a “hundred”.
2.NBT.A.1a.2. Apply the ability to count by tens.
2.NBT.A.1b. Major Standard: 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 a special case: The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (x hundreds and 0 tens and 0 ones).
