3rd Grade Math Resources

Third grade math builds on foundational skills in addition and subtraction while introducing new concepts such as multiplication, division, fractions, and geometric measurement. Students also explore area and perimeter of simple shapes, interpret data through graphs and plots, and apply measurement skills to real-world problems involving time, mass, and volume. These topics help learners develop problem-solving strategies and a deeper understanding of numbers and their relationships.

Education.com’s Third Grade Math collection offers over 1,600 resources, including worksheets, guided lessons, hands-on activities, and interactive exercises, many aligned with Common Core State Standards. Students strengthen number sense through place value practice, rounding, and multi-digit operations, while building multiplication fluency using skip counting, arrays, and repeated addition. Division concepts are introduced using equal groups, number lines, and strip models to connect with multiplication understanding. Fraction lessons use visual models to develop conceptual understanding, and geometry resources guide students through area, perimeter, and shape classification.

Resources are available in both print and digital formats to support different learning styles, and filters make it easy for teachers and parents to find activities by topic, skill, or activity type. By engaging with these materials, third graders build confidence, reinforce classroom learning, and prepare for the more advanced math concepts they will encounter in fourth grade and beyond.
