2-D Figures

Objective

I can compare attributes of 2-dimensional figures with 3-

dimensional figures by drawing and constructing nets and models.

I can identify and classify the properties of two-dimensional (2-D) shapes using appropriate vocabulary.

Today

Look at these two figures. Think to yourself... What is the difference between these two figures?

Set

A two dimensional shape only measures two things; length and width

A three dimensional shape measures three things; length, width, and height

2D vs. 3D shapes

Triangle

*three sides*three vertices

Equilateral Triangle Right Triangle

Quadrilateral

*four sides*four vertices

Square Rectangle

Pentagon

*five sides*five vertices

Hexagon

*six sides*six vertices

Octagon

*eight sides*eight vertices

Name that Shape

ClosureWrite down the names of the five shapes we learned about today and draw a sketch of

them.You have 3 minute to do this.

Independent PracticeOn your laptops you will create a power point on the five figures we just learned about. You will title it : 2-Dimensional Figures Please include:• Name of figure on top•How many vertices•How many edges•Add a picture of figure
