Angle Barrier Game

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 specified size. Recognize right triangles as a category, and identify right triangles.
Sample Activities:
Quadrilateral Criteria
Right Triangles on the Geoboard
Also included in 4th Grade Math Centers:
Classifying 2D Figures 
Constructing Quadrilaterals
Sorting Right Triangles

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.
Sample Activity:
Symmetry in Regular Polygons
Symmetrical Designs
