Essential Vocabulary for 3rd Grade Math Success | Learn Key Computation Terms

Learn 35 essential 3rd grade math vocabulary words for computation! This short animation helps third graders master key math terms for addition, subtraction, comparisons, multiplication, and division – perfect for building strong number sense and confidence. Each term and definition is spoken aloud, and most include an example. After each definition is a brief pause so you can stop the video and discuss or review together. The order follows Georgia’s mathematics content, which incorporates the Standards of Mathematical Practices and the Mathematical Modeling Framework through four big ideas, including numerical reasoning. In third grade, students deepen their understanding of place value, include multiplication and division of whole numbers, and begin working with fractions. These third-grade computation vocabulary terms will set you up for success!
