Overview

• NCTM Standards
• Geometry 6-8
• Analyze characteristics and properties of two-
  and three-dimensional geometric shapes and
  develop mathematical arguments about geometric
  relationships
• Understand relationships among the angles, side
  lengths, perimeters, areas, and volumes of
  similar objects
• Use visualization, spatial reasoning, and
  geometric modeling to solve problems
• Draw geometric objects with specified properties,
  such as side lengths or angle measures

• Assessment
• Students will be assessed on their completion of
  their worksheet, accuracy of information about
  quadrilaterals, and understanding the properties
  of different quadrilaterals.

Introduction

• This topic splash activity is designed to
  introduce you to quadrilaterals. You will be
  introduced to three different types of four-sided
  polygons, rectangles, parallelograms, and
  trapezoids. You will search the internet to
  complete the worksheet and answer questions based
  on each one of these quadrilaterals. You will
  then work in groups and create your own
  quadrilateral using the internet.

Quadrilaterals

• Rectangle
• Quadrilaterals - Square, Rectangle, Rhombus,
  Trapezoid, Parallelogram
• Isosceles Trapezoid
• Complete the Quadrilateral Worksheet. To find
  the properties and definition of a rectangle,
  rhombus, and parallelogram, visit these websites.
• Before doing this, visit the Floor Tiles website.

Conclusion/Extensions

• You will now be able to connect your knowledge
  of angles, lines, and congruency to many
  different polygons, now including quadrilaterals.
• Discussion of the importance of knowing the
  characteristics of different types of
  quadrilaterals.
• To learn more about properties of quadrilaterals,
  visit these websites
