Key takeaways

  • In 3rd grade math, students develop a deeper understanding of multiplication and division, fractions, and measurements.
  • Word problems for 3rd graders require more advanced comprehension skills.
  • Place Value: Understanding place value helps us read and write numbers correctly and compare their values.
  • Look for opportunities for your child to practice their math at home–worksheets, math games, or a math practice app will help strengthen new mathematical knowledge. While consistency is key, math practice for 3rd graders should be engaging and fun.

In addition to reviewing and strengthening the skills learned in previous years, 3rd graders learn multiplication and division, explore fractions, calculate measurements, and more. Also, word problems for 3rd graders are often multi-step, requiring students to understand what operations to perform and how to perform them correctly. 

This list of 3rd grade math problems is intended to reinforce concepts students have already been taught. The list is divided into sections: addition, subtraction, multiplication, division, fractions, measurement, and multi-step problems. These sections allow students to specifically focus their practice, but feel free to skip around and choose the 3rd grade math practice problems that best suit your child’s needs.
