South Carolina Standards
South Carolina 1st Grade Math Standards
All 30 South Carolina math standards for 1st 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
2 standards1.DPSR.1.1
Sort pictures or objects into three or more groups, with no more than 10 items in any one group.
1.DPSR.1.2
Write a survey question with up to three choices, chart the answers on a graph that counts by ones, and use it to answer one-step questions like how many in all.
Measurement, Geometry, and Spatial Reasoning
10 standards1.MGSR.1.1
Put three objects in order by length, from shortest to longest or longest to shortest, by lining them up side by side.
1.MGSR.1.2
Estimate, then measure, how long something is by laying same-size objects like paper clips end to end with no gaps or overlaps.
1.MGSR.1.3
Tell and write time to the hour and half hour on analog and digital clocks, like 3:00 and 3:30.
1.MGSR.1.4
Name and write the value of a penny, nickel, dime, quarter, and one, five and ten dollar bills, using the ¢ sign for coins and $ for bills.
1.MGSR.1.5
Count a set of all pennies, all nickels or all dimes to find the total value, up to one dollar, like 6 dimes is 60¢.
1.MGSR.2.1
Sort a mixed group of polygons and explain the sorting rule, like putting all the shapes with four sides together.
1.MGSR.2.2
Name and describe the features of circles, triangles, squares, rectangles, rhombuses and hexagons, plus cubes, cones, cylinders, spheres and square pyramids.
1.MGSR.2.3
Find circles, rhombuses, hexagons, triangles, squares and rectangles, plus cones, cubes, cylinders, spheres and square pyramids, in everyday objects and describe each.
1.MGSR.2.4
Sort circles, triangles, squares, rectangles, rhombuses, hexagons, spheres, cubes, cones, cylinders and square pyramids as flat or solid and explain why in math terms.
1.MGSR.2.5
Compare two flat shapes or two solids of different sizes and turns using math words, like a tall thin rectangle and a small tilted square, or a cone and a cylinder.
Numerical Reasoning
8 standards1.NR.1.1
Read, write and show numbers up to 100 with blocks, drawings, digits, words like 4 tens 7 ones, and expanded form like 47 = 40 + 7.
1.NR.1.2
Show and explain that numbers from 1 to 99 are made of tens and ones, and that a digit's value depends on its place, like the 3 in 35 meaning 30.
1.NR.1.3
Build and break apart numbers 1 to 99 as tens and ones in more than one way, like 35 as 3 tens 5 ones or 2 tens 15 ones, showing each with models or equations.
1.NR.1.4
Use place value to find one more, one less, ten more and ten less than any number up to two digits, like 46, 44, 55 and 35 for 45.
1.NR.2.1
Count forward or backward by ones from any starting number up to 120, crossing into each new decade correctly, like 38, 39, 40, 41.
1.NR.2.2
Skip count by fives and tens to 100, starting from any multiple of five, and notice place value patterns, like the ones digit going 5, 0, 5, 0.
1.NR.3.1
Compare two numbers up to 100 shown in different ways and say whether the first is greater than, less than or equal to the second.
1.NR.4.1
Cut circles, squares and rectangles into halves or fourths in more than one way, naming each equal piece a half or a fourth.
Patterns, Algebra, and Functional Reasoning
10 standards1.PAFR.1.1
Decide whether an equation within 10 is true or false and explain why, with equations written in different ways, like 7 = 3 + 4 or 5 + 2 = 6 + 1.
1.PAFR.1.2
Build and break apart numbers up to 20 in several ways, writing an equation for each, like 15 = 10 + 5 and 15 = 8 + 7.
1.PAFR.1.3
Solve story problems within 20 about adding to, taking from and combining parts, with the result, change, total, one part or both parts unknown.
1.PAFR.1.4
Add and subtract within 10 quickly and correctly using flexible strategies, like counting on or making 10.
1.PAFR.1.5
Use the commutative property to add two numbers with sums through 20, explaining why 3 + 8 and 8 + 3 give the same total.
1.PAFR.1.6
Find the missing number in an addition or subtraction equation within 10, like 5 plus what number makes 8.
1.PAFR.1.7
Add a two-digit number to a one-digit number or a multiple of 10, within 99, using models, place value, properties and the link to subtraction to justify the sum.
1.PAFR.1.8
Subtract one multiple of 10 from another between 10 and 90, like 70 minus 30, write the equation, and explain the thinking.
1.PAFR.2.1
Make, describe and continue a growing pattern of shapes by one more step, like 1 square, then 2, then 3.
1.PAFR.2.2
Make, describe and continue AB, AAB, ABB and ABC repeating patterns by three more items, like star, moon, moon, star, moon, moon.
