What do 3rd graders learn in math?

Third grade is a big year for math. Kids move from adding and subtracting to multiplying, dividing and working with fractions. Here are the main skills:

  • Multiplication and division. Kids learn what multiplying means using equal groups and arrays. By the end of the year, they should know their times tables up to 10 x 10.
  • Fractions. Students learn that a fraction is a part of a whole. They place fractions on a number line, find equal fractions, and compare fractions.
  • Place value and rounding. Kids add and subtract numbers up to 1,000 and round numbers to the nearest 10 or 100.
  • Area and perimeter. Students find the area of shapes by counting square units, then by multiplying. They also find the distance around a shape.
  • Measurement and data. Kids tell time to the nearest minute, measure weight and liquid volume, and read and make bar graphs and line plots.
  • Shapes. Students sort shapes by their features and learn about groups like quadrilaterals.
  • Word problems. Kids solve two-step word problems using all four operations.

How to use these 3rd grade math resources

Use a worksheet to introduce a new skill, a game for extra practice, or a short quiz to check what kids know. Every resource is tagged with its Common Core standard, so it's easy to find the right fit. Teachers can assign work to the whole class or to small groups. Parents can use them for homework help or summer practice.
