South Carolina College- and Career-Ready Mathematical Process Standards
2nd Grade Math
2.G.1 Identify triangles, quadrilaterals, hexagons, and cubes. Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces
2.ATO.1 Solve one- and two-step real-world/story problems using addition (as a joining action and as a part-part-whole action) and subtraction (as a separation action, finding parts of the whole, and as a comparison) through 99 with unknowns in all positions.
2.ATO.2 Demonstrate fluency with addition and related subtraction facts through 20.
2.ATO.3 Determine whether a number through 20 is odd or even using pairings of objects, counting by twos, or finding two equal addends to represent the number (e.g., 3 + 3 = 6).
2.NSBT.1 Understand place value through 999 by demonstrating that: a. 100 can be thought of as a bundle (group) of 10 tens called a “hundred”; b. 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; c. 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 <).
