4.G.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
4.G.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.
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.
Symmetry Around Us
This playlist contains four activities to help students explore symmetry in geometric figures. Symmetry Game: Students are presented with a set of review problems and must identify one or more lines of symmetry in a given shape. This DLA shows folds along lines of symmetry and gives other informatio...
