3rd Grade

Students investigate numbers, ways of representing numbers, relationships among numbers, and number systems.

Students perform mathematical operations and determine how they relate to one another

Students investigate patterns, functions, and quantitative relationships and apply that knowledge to modeling, analyzing, or solving mathematical and real-world problems.

Students use symbolic forms, operations, and properties to represent, model, solve, and analyze mathematical situations and structures.

Students explore properties, relationships, and transformations of shapes and space using coordinate geometry and other representational systems.

Students explore concepts and practical applications of units, geometrical constructions, and measurements of plane and geometric shapes and space.

Students demonstrate statistical thinking and apply statistical methods to collect, organize, analyze, display, and make inferences based on data.

Students use concepts of chance and probability to explain outcomes of real-life situations.

Round whole numbers to the nearest 10 or 100 using place value understanding
