Angles as Turns, Classification, and Protractor Measurement

Identify and draw points, lines, line segments, rays, horizontal, vertical, oblique, parallel, and perpendicular lines, and understand paths between points.

Understand angles as geometric turns, classify acute, right, obtuse, and straight angles, and measure and draw benchmark angles using protractors.

Classify, describe, and compare triangles and quadrilaterals by side lengths, angle types, and parallel or perpendicular side properties.

Partition 2D shapes into equal-area parts, represent each part as a unit fraction of the whole, and understand that equal-area parts can have different shapes.

Analyze properties of 3D solids (prisms, pyramids, cylinders, cones, spheres), connect solids to 2D nets, and construct 3D geometric models.

Identify lines of symmetry, perform and describe reflections, translations, and rotations, and analyze geometric patterns in nature and art.

Read and create grid maps, navigate using cardinal and intercardinal compass directions and perspective relative positions, and interpret multi-view elevations of 3D objects.
