A What? A What? A Quadrilateral
Do all quadrilaterals have right angles? Investigate attributes of these shapes with geometers, starting by finding four-sided shapes in the classroom. Learners conduct a think-pair-share search for quadrilaterals they can see then examine a bag of shapes on their desk (you'll need to prepare these ahead of time).

Lines of Symmetry for Quadrilaterals
Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your class to look for patterns between the angles and side lengths of each shape and the lines of symmetry they found.

An Introduction To Quadrilaterals
Young geometers investigate and apply properties of quadrilaterals. After a review and discussion of key terms, students use a computer applet to explore four-sided figures and classify them according to their attributes. The exploration can be done individually or in groups.

Create, Classify, and Sort Quadrilaterals
Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among rectangles, squares, rhombuses, and more!

Investigating Segments in a Quadrilateral
Investigate the properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral. In this properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral lesson, students use Cabri Jr.

What is a Trapezoid? (Part 1)
Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class discussions in order to reach agreement on a single definition for trapezoids.

The quadrilateral is a very interesting shape. Have your class construct midpoint quadrilaterals within quadrilaterals on their Ti-Nspire. They measure the length and angle measures of sides and angles of the midpoint quadrilateral. Full instructions on how to use the technology are included.

New Review Symmetries of a Quadrilateral I
Learners examine the properties of quadrilaterals from the point of view of rigid motion. Different types of quadrilaterals are characterized by their symmetries, so learners explore the symmetries of a described quadrilateral to identify its type.

Properties of Special Quadrilaterals
Teach your mathematicians how to identify the properties of quadrilaterals. For this geometry lesson, high schoolers solve for missing angles and sides of a special quadrilateral. They use the TI to move the sides around and create different angles.

Say Hello to the Quadrilateral Family!
Seventh graders engage in the study of quadrilaterals and how to classify them. They practice constructing different quadrilaterals using intersecting lines on geoboards. This is ideal for the kinesthetic learners in class to keep them interested.
