**4th GRADE GEOMETRY ACTIVITIES**

**Draw and identify lines and angles, and classify shapes by properties of their lines and angles**

**4.G1** Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

**Possible Activities:**

Geoboard Line Segments

Angles on the Geoboard

Angle Barrier Game

**4.G2 **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:**

Right Triangles on the Geoboard

Isosceles Triangles on the Geoboard

Constructing Quadrilaterals

Quadrilateral Criteria

Classifying Triangles 1

Classifying Triangles 2 Triangles Pack

Triangles on the Geoboard

**4.G3 **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:**
