- CCSS.Math.Content.3.G.A.1
- Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that...
- CCSS.Math.Content.4.G.A.1
- Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
- CCSS.Math.Content.4.G.A.2
- Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a...
- CCSS.Math.Content.4.MD.C.5
- Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
- CCSS.Math.Content.4.MD.C.6
- Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
- CCSS.Math.Content.4.MD.C.7
- Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle...
