Geometric Shapes and Measures Geometric Shapes and Measures: Points, Lines, and Angles Measure and estimate lengths. Identify and draw parallel and perpendicular lines. Identify, compare, and draw different types of angles (e.g., a right angle, and angles larger or smaller than a right angle). Use informal coordinate systems to locate points in a plane. Geometric Shapes and Measures: Two- and Three- dimensional Shapes Use elementary properties to describe and compare common two- and three- dimensional geometric shapes, including line and rotational symmetry. Relate three-dimensional shapes with their two-dimensional representations. Calculate perimeters of polygons; calculate areas of squares and rectangles; and estimate areas and volumes of geometric figures by covering with a given shape or by filling with cubes. Note: Fourth grade geometric shapes items will involve circles, triangles, quadrilaterals, and other polygons, as well as cubes, rectangular solids, cones, cylinders, and spheres. Data Display: Reading, Interpreting, and Representing Read, compare, and represent data from tables, pictographs, bar graphs, line graphs and pie charts. Use information from data displays to answer questions that go beyond directly reading the data displayed (e.g., solve problems and perform computations using the data, combine data from two or more sources, make inferences, and draw conclusions based on the data).
