Third-Grade Math Curriculum: What Students Will Learn

In third grade, students will be expected to know addition, subtraction, multiplication, and division facts and use them in equations and word problems. Third-graders should know how to place values for numbers up to six digits, read and write large numbers, and round and compare numbers. They should understand equivalent fractions and be able to compare fractions.

In addition, third-graders should know how to round decimals to the one-hundredth place, recognize and write patterns, add four-digit numbers, and do mental addition and subtraction. They should use number lines, know how to subtract with regrouping, read and make graphs, and recognize two-dimensional shapes.

That may seem like a lot of math facts for a third-grader to master! The major concepts of third-grade math curriculum are number theory and systems, algebraic thinking, geometrical figures and objects, measurement of length, weight, time, and temperature, probability, and data analysis. The path to mastering math can be fraught with challenges, and third grade can be especially challenging, as many new and complicated math theories are introduced.
