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.

Sample Activities:
Alphabet Lines 
Angles on the Geoboard
Also included in 4th Grade Math Centers:
** Geoboard Line Segments
** Name Geometry

** Angle Barrier Game

Name Geometry

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
Also included in 4th Grade Math Centers:
** Symmetrical Coin Design
** Symmetry on the Geoboard
** Symmetrical Letters
** Symmetrical Designs
