Third Grade Curriculum Guide
THIRD GRADE AT THE ORCHARD SCHOOL
Mathematics
Third-grade math at The Orchard School emphasizes problem-solving as well as computational fluency. Students work individually, with a partner, and in flexible groups across the grade, often employing manipulative materials and technology. Various forms of ongoing assessments are used to meet students at their “just right” math level. Numerous enrichment activities take the form of differentiated math stations, hands-on learning, written explanation of learning, logic and problem-solving strategies, and puzzles.
Third-graders develop as mathematicians by exploring these areas:
• Identifying decimal place value to hundredths and expanded notation and place value to one million. • Using computational estimation and paper and pencil strategies. • Developing understanding of math facts in multiplication and division. • Using a variety of solution strategies to relate multiplication and division as inverse operations. • Adding and subtracting with regrouping using four-digit numbers. • Multiplying and dividing numbers through to 100. • Using fractions to represent parts of a whole, parts of a set, and points and distances on a number line. • Finding patterns on number grids. • Identifying, drawing, and labeling segments, lines, rays, angles, symmetry, and parallel and intersecting lines. • Investigating, describing, and reasoning about decomposing, combining, and transforming polygons to make other polygons. • Telling time to the nearest minute. • Measuring to the nearest quarter-inch and whole centimeter. • Solving problems involving area and perimeter. • Predicting outcomes and discussing probability. • Constructing and analyzing frequency tables, bar graphs, picture graphs, and line plots.
