### CC.2.NBT. Number and Operations in Base Ten

### 2.NBT.1. 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:

2.NBT.1.a.
100 can be thought of as a bundle of ten tens -- called a ''hundred.''
