4th Grade Math Worksheets & Resources

What do 4th graders learn in math?

In fourth grade, students build on whole-number operations and start working with fractions and decimals in more detail. They also learn to measure angles and classify shapes.

• Multi-Digit Operations. Students multiply a whole number of up to four digits by a one-digit number and multiply two two-digit numbers. They also divide with remainders and solve multi-step word problems.
• Fractions and Decimals. Fourth graders explain equivalent fractions, compare fractions with different numerators and denominators, and add and subtract fractions with like denominators. They also write fractions with denominators 10 or 100 as decimals.
• Place Value and Rounding. Students read and write multi-digit whole numbers, compare them, and round to any place. They use place value understanding to perform operations.
• Geometry and Angles. Kids draw and identify points, lines, line segments, rays, and angles. They measure angles with a protractor and classify shapes by their lines and angles.
• Measurement and Data. Students convert measurements within a system, solve area and perimeter problems, and make line plots to display data. They also understand angle measures as additive.
• Factors, Multiples, and Patterns. Fourth graders find factor pairs for whole numbers and identify prime and composite numbers. They generate number or shape patterns that follow a rule.
