  • 4.MD.5. Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

    (Common Core Mathematics /// Grade 4 /// Measurement And Data /// Geometric Measurement: Understand Concepts Of Angle And Measure Angles)

  • 4.MD.6. Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

    (Common Core Mathematics /// Grade 4 /// Measurement And Data /// Geometric Measurement: Understand Concepts Of Angle And Measure Angles)

  • 4.MD.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 measures of the parts. Solve addition and subtraction problems to find unknown angles on a diagram in real world and mathematical problems, e.g., by using an equation with a symbol for the unknown angle measure.

    (Common Core Mathematics /// Grade 4 /// Measurement And Data /// Geometric Measurement: Understand Concepts Of Angle And Measure Angles)

  • 4.G.1. Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

    (Common Core Mathematics /// Grade 4 /// Geometry /// Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles)

  • 4.G.3. Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

  • Make observations to construct an evidence-based account that objects can be seen only when illuminated.

    (Next Generation Science Standards /// Grade 1 /// Physical Science /// Waves and their Applications in Technologies for Information Transfer )

  • Plan & conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.

    (Next Generation Science Standards /// Grade 1 /// Physical Science /// Waves and their Applications in Technologies for Information Transfer )

  • Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.

    (Next Generation Science Standards /// Grade 4 /// Physical Science /// Waves and their Applications in Technologies for Information Transfer)

  • Develop & use a model to describe that waves are reflected, absorbed, or transmitted through various materials. [Both light & mechanical waves. ]

    (Next Generation Science Standards /// Middle School /// Physical Science /// Waves and their Applications in Technologies for Information Transfer )

  • 2.b. Light is reflected from mirrors and other surfaces.

    (CA Science /// Grade 3 /// 01. Physical Sciences /// 2. Light has a source and travels in a direction.)

  • 6.f. Light interacts with matter by transmission (including refraction), absorption, or scattering (including reflection).

    (CA Science /// Grade 7 /// 06. Physical Science: Physical Principles in Living Systems /// 6. Physical principles underlie biological structures and functions.)

  • 6.g. The angle of reflection of a light beam is equal to the angle of incidence.

    (CA Science /// Grade 7 /// 06. Physical Science: Physical Principles in Living Systems /// 6. Physical principles underlie biological structures and functions.)

  • 2.5 Identify, describe, and classify common three-dimensional geometric objects (e.g., cube, rectangular solid, sphere, prism, pyramid, cone, cylinder).

    (CA Mathematics /// Grade 3 /// 03. Measurement and Geometry /// 2.0 Students describe and compare the attributes of plane and solid geometric figures and use their understanding to show relationships and solve problems.)

  • 3.4 Identify figures that have bilateral and rotational symmetry.

    (CA Mathematics /// Grade 4 /// 03. Measurement and Geometry /// 3.0 Students demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve problems.)

  • 3.6 Visualize, describe, and make models of geometric solids in terms of the number of faces, edges, and vertices; interpret 2-D representations of 3-D objects; and draw patterns for a solid, that when cut and folded, will make a model of the solid.

    (CA Mathematics /// Grade 4 /// 03. Measurement and Geometry /// 3.0 Students demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve problems.)
