WASHINGTON GRADE 3 MATHEMATICS STANDARDS
Students learn about multiplication and division and their relationship to each other, as well as how these operations relate to addition and subtraction. As they solve problems involving multiplication and division, students extend their work with simple equations and lay the foundation for later work with fractions.
Students learn about fractions and how they are used. They begin to understand that fractions are special kinds of numbers so they will be ready to use them with operations and in problems in later grades.
Geometry, Measurement, Algebra
Students continue to work with two-dimensional figures, identifying special characteristics of lines, angles, triangles, and quadrilaterals. They begin to connect numbers, operations, and geometry by measuring and calculating perimeters.
Numbers, Operations, Algebra, Measurement, Data/Statistics/Probability
Students strengthen their understanding of numbers in preparation for algebra by using number sentences and equations to connect different mathematical expressions for the same value. Students continue to work with addition and subtraction, using large numbers and applying them in new contexts. Students formalize their work with measurement to include standard units for temperature, weight, and capacity.
Reasoning, problem solving, and communication
Students in grade three solve problems that extend their understanding of the core concepts of multiplication, division, fractions, and two-dimensional figures. Students make strategic decisions that bring them to reasonable solutions. They use pictures, symbols, and mathematical language to explain the reasoning behind their decisions and solutions. They further develop their problem-solving skills by making generalizations about the processes used and applying these generalizations in similar problem situations.
