Draw and identify lines and angles, and classify shapes by properties of their lines and angles
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.
Possible Activities:
Alphabet Lines
Geoboard Line Segments
Angles on the Geoboard
Angle Barrier Game

Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
Possible Activities:
Classifying 2D Figures 
Constructing Quadrilaterals
Quadrilateral Criteria
Right Triangles on the Geoboard

4.G.A.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.
Possible Activities:
Symmetry on the Geoboard
Symmetry in Regular Polygons
Symmetrical Coin Design
