1st Grade Math in South Carolina

South Carolina 1st grade math follows the SC College Career Ready Standards, covering key skills in addition and subtraction, place value, measurement, geometry, and data. These standards build a strong foundation that students carry into 2nd grade and beyond.

Addition and Subtraction

First graders learn to add and subtract within 20, solve word problems, and understand how addition and subtraction relate. They practice adding three whole numbers, applying properties of operations, and finding unknown values in equations. StudyPug has step-by-step video lessons for every one of these skills.

Place Value and Two-Digit Numbers

Students learn that two-digit numbers are made of tens and ones. They count to 120, compare two-digit numbers using >, =, and <, add within 100, and mentally find 10 more or 10 less than any number. These place value skills are essential for success in 2nd grade math.

Measurement and Time

1st graders order objects by length, measure using whole number units, and tell time in hours and half-hours using both analog and digital clocks. StudyPug's video lessons make these hands-on concepts easy to understand at home.

Geometry and Shapes

Students learn to identify defining attributes of shapes, compose 2D and 3D shapes into new figures, and partition circles and rectangles into equal shares. These early geometry skills connect directly to fractions in later grades.
