**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**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.

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
