Draw and identify lines and angles / classify shapes by their properties

Fourth grade goals:

• • Draw points, lines, line segments, rays, angles, and perpendicular and parallel lines.

  • Identify points, lines, line segments, rays, angles, and perpendicular and parallel lines in shapes.

  • Classify shapes based on their parallel/perpendicular lines and specific angles.

  • Identify shapes with lines of symmetry.

  • Draw lines of symmetry.

When students enter fourth grade:

• • Students should be able to identify shapes such as rhombuses, rectangles, etc.

  • Students should be able to explain what makes a shape a quadrilateral.
