All files are in PDF format. Sample activities listed in **blue** are available for immediate download. Activities listed in ****grey **are available in our **4th Grade Math Centers eBook.**

**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:**

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.
