Overview NCTM Standards Assessment 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.

Student Materials Introduction Internet Activities

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.

Internet Activities Floor Tiles

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: Polygons - Quadrilaterals - First Glance The Quadrilateral Family Figures and polygons
