Geometry: Defining Shapes Created by: Ms. Yoder Introduction Lesson Quiz

Introduction This lesson is intended for second grade math students. Learning Objective: Upon the completion of this Power. Point, students will be able to recognize and identify shapes having specific attributes. Common Core Standard to be covered: Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

Lesson Important Definitions: 2 -dimensional A shape that has a width and a length but no thickness. 3 -dimensional An object that has length, width, and height, like any object in the real world.

Lesson Vertex A (plu. Vertices) point where two or more lines meet Vertices Angle The space between two intersecting lines Angles

Lesson Edge One Face A of the lines that make up any shape Edge flat surface on a 3 -dimensional shape Face

Triangles 2 -dimensional 3 vertices 3 angles 3 edges All edges must be straight but can vary in length. Triangle

Square Quadrilaterals 2 -dimensional 4 vertices 4 angles 4 edges Rectangle Rhombus All edges must be straight but can vary in length. Trapezoid

Pentagons 2 -dimensional 5 vertices 5 angles 5 edges All edges must be straight but can vary in length. Pentagon

Hexagons 2 -dimensional 6 vertices 6 angles 6 edges All edges must be straight but can vary in length. Hexagon

Cubes 3 -dimensional 8 vertices 24 angles 6 faces 12 edges All Cube edges must be straight AND the same length.
