Grade 3 Math

The third grade curriculum is designed to develop students' knowledge of and facility with place value, multiple digit addition and subtraction, multiplication and division, compatible numbers and estimation. Students construct models and complete fact families to demonstrate their understanding of the relationship between the operations. They practice strategies to learn addition and subtraction facts with automaticity and learn skills in solving basic multiplication facts. They also practice identifying and implementing a variety of problem solving methods and learn to communicate how they understand, plan for, solve, and check number stories. Third graders practice skills and strategies when solving multi-step number stories, and they expand their understanding of fractions when identifying, comparing, and combining fractional amounts. Students also study geometric concepts and skills that encompass two- and three-dimensional figures.

Our third grade students will:

  • use place value understanding and properties of operations to solve multi-digit arithmetic problems
  • develop an understanding of fractions as numbers
  • represent and solve problems involving multiplication and division
  • understand properties of multiplication and the relationship between multiplication and division
  • solve problems involving the four operations and identify and explain patterns in arithmetic
  • reason with shapes and their attributes
  • recognize perimeter as an attribute of plane figures
  • understand concepts of area and relate area to multiplication and to addition
  • solve problems involving measurement and estimation of length, intervals of time, masses of objects, and liquid volumes
  • represent and interpret data
  • construct and analyze tables, bar graphs, and picture graphs
  • develop and practice problem solving techniques
