1 CCS.2.G.1 Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.1 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

2 Table of Contents Objectives
I can identify triangles and quadrilaterals I can identify pentagons and hexagons I can identify cubes

3 Building Background The purpose of the following slides is to allow students to share what they already know, make connections, and give students more background information that may be helpful. Thinking Maps Discussion Visual Aids

4 What we know about measurement
Prior Knowledge What we know about measurement

5 Shapes are everywhere!!

6 Vocabulary Edge (Side): a straight line or segment that is part of a shape. Angle: the place where two straight lines or segments of a shape meet. Polygon: a closed figure formed by line segments. Vertex (plural vertices):is a point where two or more straight lines meet. Face: A face is a flat surface of a 3D solid.

7 Edge (Sides): a straight line or segment that is part of a shape.
edge of the square

8 Angle: the inside place where two straight lines or segments of a shape meet.

9 Polygon: a closed figure formed by line segments.

10 Vertex (plural vertices): is a point where two or more straight lines meet.

11 Face: A face is a flat surface of a 3D solid.
