South Carolina 3rd Grade Math Standards

All 30 South Carolina math standards for 3rd 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.

30 standards

Data, Probability, and Statistical Reasoning

3 standards
3.DPSR.1.1
Organize category and number data from surveys and experiments in tables, scaled picture or bar graphs, or dot plots with titles, labels and scales of 1, 2, 5 or 10.
3.DPSR.1.2
Solve one-step real-life problems using whole number data from tables, scaled picture or bar graphs, or dot plots with scales of 1, 2, 5 or 10.
3.DPSR.2.1
List every possible outcome of a simple event, like heads or tails for a coin flip or 1 to 6 for a number cube.

Measurement, Geometry, and Spatial Reasoning

10 standards
3.MGSR.1.1
Find the area of squares and rectangles in problems by covering them with unit squares and counting how many it takes.
3.MGSR.1.2
Find the perimeter of any triangle or four-sided shape, regular or irregular, by adding its known side lengths.
3.MGSR.1.3
Decide whether a real-life job calls for area or perimeter, like carpet for a floor versus a fence around a yard.
3.MGSR.2.1
Count any mix of pennies, nickels, dimes and quarters up to $5 and write the total with a dollar sign and decimal point, like $3.65.
3.MGSR.2.2
Read analog and digital clocks to the nearest minute, write the time, and mark it AM or PM, like 4:37 PM.
3.MGSR.2.3
Add and subtract time intervals to find how much time has passed, to the nearest half hour, like 9:00 to 11:30 being 2 and a half hours.
3.MGSR.2.4
Estimate and then measure lengths and distances to the nearest half inch and to the nearest whole centimeter.
3.MGSR.2.5
Pick the best unit for measuring liquid in real life, from fluid ounces, cups, pints, quarts and gallons to milliliters and liters.
3.MGSR.3.1
Draw and describe acute, right, obtuse and straight angles, and find them in triangles and quadrilaterals.
3.MGSR.3.2
Draw, describe and spot points, lines, line segments and rays, plus intersecting, perpendicular and parallel lines, including inside flat shapes.

Numerical Reasoning

10 standards
3.NR.1.1
Read, write and place whole numbers up to 999,999 on a number line, and write them in digits, words, place value names and expanded form.
3.NR.1.2
Break apart and build four-digit numbers in different ways with thousands, hundreds, tens and ones, like 3,450 as 34 hundreds and 5 tens.
3.NR.1.3
Compare two whole numbers up to 999,999 by the value of their digits and record it with the greater than, less than or equal sign.
3.NR.1.4
Round any whole number up to 1,000 to its nearest ten or hundred, like 467 becoming 470 or 500.
3.NR.2.1
Explain that a unit fraction is one of 2, 3, 4, 6 or 8 equal parts of a whole, and name each part, like 1/6 for one of six pieces.
3.NR.2.2
Show fractions from 0 to 1 with objects, sets, area models and number lines, and write them in numbers and words, with denominators 2, 3, 4, 6 or 8.
3.NR.2.3
Write whole numbers as fractions and spot fractions equal to whole numbers, like 3 = 3/1 or 8/4 = 2, with denominators 1, 2, 3, 4, 6 or 8.
3.NR.2.4
Put unit fractions together to make amounts up to 5 and write them as mixed numbers or fractions over 1, like 7/4 = 1 3/4, with denominators 2, 3, 4, 6 or 8.
3.NR.2.5
Recognize when two fractions between 0 and 1 name the same amount, like 1/2 and 2/4, with denominators 2, 3, 4, 6 or 8.
3.NR.2.6
Compare two fractions between 0 and 1 of the same whole that share a numerator or denominator, like 3/8 is less than 3/4, using denominators 2, 3, 4, 6 or 8.

Patterns, Algebra, and Functional Reasoning

7 standards
3.PAFR.1.1
Add and subtract numbers up to 1,000 using a strategy, like adding the hundreds, tens and ones separately.
3.PAFR.1.2
Multiply with factors 0 to 10 and divide by 1 to 10 using models like equal groups or arrays, and write a matching equation.
3.PAFR.1.3
Multiply numbers 0 to 10 quickly and correctly and divide using the matching facts, like 7 × 8 = 56 so 56 ÷ 8 = 7.
3.PAFR.2.1
Find the missing number in a real-life multiplication or division problem, whether it is a factor, product, dividend, divisor or quotient.
3.PAFR.2.2
Solve one-step and two-step real-life problems that use adding and subtracting with numbers up to 1,000.
3.PAFR.2.3
Find, make and continue number patterns that add or subtract the same amount, giving the next three numbers, like 12, 19, 26, 33.
3.PAFR.2.4
Understand that if a number from 1 to 10 is a factor of a whole number, that whole number is its multiple, like 24 is a multiple of 3, 4, 6 and 8.
