Teacher Notes
Point, line segments, and angles can be classified by their properties as well as basic foundations of geometric shapes. Polygons can have similar features and still be unique because of the characteristics of the elements that were used to create them.

Two-dimensional figures may be classified using different characteristics such as parallel or perpendicular lines or by angle measurement
Student Knowledge Goals
*I know the definitions of and can draw and describe the following geometric terms:
Points
Lines (parallel and perpendicular)
Line segments
Rays
Angles (right, acute, obtuse and straight)

*I can explain the difference between a line, a line segment, and a ray.

Students must know and be able to identify the following:

Lines (parallel and perpendicular)

Angles (acute, obtuse, and right)

Triangles (acute, obtuse, and right)

Students must know and be able to identify the following (taught in previous grades):

Cube

Half/Quarter Circle

Hexagon

Pentagon

Polygon

Quadrilateral

Rectangle

Rhombus/Rhombi

Square

Trapezoid

Triangle
