South Carolina Standards & Learning
SC.PS. South Carolina College- and Career-Ready Mathematical Process Standards
PS.4. Connect mathematical ideas and real-world situations through modeling.
PS.4c. Make assumptions and estimates to simplify complicated situations.
SC.2.NSBT. Number Sense and Base Ten
2.NSBT.1. Understand place value through 999 by demonstrating that:
2.NSBT.1a. 100 can be thought of as a bundle (group) of 10 tens called a “hundred”.
2.NSBT.1b. The hundreds digit in a three-digit number represents the number of hundreds, the tens digit represents the number of tens, and the ones digit represents the number of ones.
2.NSBT.1c. 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.).
2.NSBT.2. Count by tens and hundreds to 1,000 starting with any number.
2.NSBT.3. Read, write and represent numbers through 999 using concrete models, standard form, and equations in expanded form.
2.NSBT.4. Compare two numbers with up to three digits using words and symbols (i.e., >, =, or <).
