In third grade math, students will use place value to read, write, represent and compare whole numbers and decimals; use a variety of methods and tools for computing with whole numbers, fractions, mixed numbers and decimals; and demonstrate fluency in multiplication facts through 10 and corresponding division facts. Students will analyze and solve multi-step problems; count money and make change using coins and dollars up through ten dollars; and develop common references for units of measure and tell time to the nearest minute. In the geometry standard, students will classify, sketch, and describe attributes of two-dimensional figures and intersecting, parallel, and perpendicular lines; identify and model three-dimensional figures; and investigate rotational symmetry and transformations. Students will develop patterns and relationships using objects, pictures, tables, and variables to solve and explain mathematical statements and make predictions; engage in surveys and experiments for data gathering, organization, and analysis; and identify, describe, and predict simple probability and outcomes through physical models, pictures, diagrams, and lists.
