South Carolina 2nd Grade Math Standards

All 27 South Carolina math standards for 2nd grade, each explained in plain English. The official wording is in South Carolina Department of Education's document, linked at the end of this page.

27 standards

Data, Probability, and Statistical Reasoning

1 standard
2.DPSR.1.1
Ask a survey question with up to four choices, show the answers in a tally chart, picture graph, dot plot or bar graph by ones, and answer one-step questions about it.

Measurement, Geometry, and Spatial Reasoning

6 standards
2.MGSR.1.1
Choose the right tool, like a ruler or yardstick, to estimate and measure lengths and distances to the nearest inch, foot or yard.
2.MGSR.1.2
Tell and write time to the nearest five minutes on analog and digital clocks, and say whether it is AM or PM.
2.MGSR.1.3
Find the value of mixed coins up to a dollar or mixed $1, $5, $10 and $20 bills up to $100, write it with ¢ or $, and solve add-to or take-from money problems.
2.MGSR.2.1
Find and describe everyday shapes: polygons with 3, 4, 5, 6 or 8 sides, circles, cubes, cones, cylinders, spheres, rectangular prisms and square pyramids.
2.MGSR.2.2
Sort shapes into polygons and non-polygons, and defend each choice using features like straight sides and a closed outline.
2.MGSR.2.3
Sort flat shapes into triangles and quadrilaterals and justify each choice, like counting three or four sides.

Numerical Reasoning

9 standards
2.NR.1.1
Read, write and show numbers up to 999 with blocks, drawings, digits, words like 3 hundreds 4 tens 2 ones, and expanded form like 342 = 300 + 40 + 2.
2.NR.1.2
Show and explain that numbers from 1 to 999 are built from hundreds, tens and ones, and that a digit's value depends on its place, like the 4 in 482 meaning 400.
2.NR.1.3
Build and break apart numbers 1 to 999 as hundreds, tens and ones in more than one way, like 245 as 2 hundreds 4 tens 5 ones or 24 tens 5 ones, using models or equations.
2.NR.1.4
Use place value to add or take away 10 or 100 from any three-digit number, like 342 becoming 352, 332, 442 or 242.
2.NR.2.1
Starting at any number within 999, count up and down by ones, tens and hundreds and describe the patterns, like 130, 140, 150 changing only the tens digit.
2.NR.3.1
Compare two numbers up to 999 shown in different ways and record the result in words and with the greater than, less than or equal sign.
2.NR.3.2
Tell which multiple of 10 a two-digit number is nearest to, like 67 is closest to 70.
2.NR.4.1
Divide circles, squares and rectangles into halves or fourths in several ways and describe the parts with words like a half of or a fourth of, not quarters.
2.NR.4.2
Explain that cutting a square, rectangle or circle into four equal parts makes smaller pieces than cutting it into two, so a fourth is less than a half.

Patterns, Algebra, and Functional Reasoning

11 standards
2.PAFR.1.1
Add and subtract two-digit numbers within 100 using a strategy, like breaking them into tens and ones, and explain why the answer is right.
2.PAFR.1.2
Decide whether an equation within 20 is true or false and explain why, even in less common forms, like 14 = 9 + 5 or 8 + 7 = 10 + 5.
2.PAFR.1.3
Solve one-step story problems within 99 about adding to, taking from, combining parts and comparing, with the missing number in any spot.
2.PAFR.1.4
Find the number that adds to any number from 0 to 99 to make exactly 100, like 63 and 37.
2.PAFR.1.5
Find sums and differences within 20 quickly and accurately with flexible strategies, like using doubles to solve 7 + 8.
2.PAFR.1.6
Use the associative property to add three numbers totaling up to 20, and explain why any grouping gives the same sum, like adding 3 + 7 first in 3 + 7 + 5.
2.PAFR.1.7
Find the missing number in an addition or subtraction equation within 20, wherever it appears, like 13 minus what number equals 6.
2.PAFR.1.8
Split up to 20 objects into two equal groups or pairs to tell if the count is even or odd.
2.PAFR.1.9
Count objects in equal groups or a rectangular array and write the total, up to 25, as a sum of equal addends, like 4 + 4 + 4 = 12 for 3 rows of 4.
2.PAFR.2.1
Describe, continue and make a growing shape pattern up to three steps long, like triangles made of 3, then 6, then 9 sticks.
2.PAFR.2.2
Make, describe and continue number patterns with a one-step adding or subtracting rule within 100, like 15, 20, 25 with the rule add 5.
