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.
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. A great resource for developing a deeper understanding of quadrilaterals.
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). The shapes should include squares, rhombi, non-regular quadrilaterals, and rectangles. They think about what all the shapes have in common as well as differences. Complete a t-chart together (included), recording attributes of all quadrilaterals and some quadrilaterals. Synthesize this information using the interactive online link which has scholars practice the skills and then take a quiz.
Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create 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!
Students differentiate between inscribed quadrilaterals and parallelograms. In this geometry lesson, students identify the shaped of the polygons when it is inscribed inside of a circle. They calculate the missing angles of the inscribed parts.
Students classify, flip, slide, and turn a quantity of quadrilaterals.
Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They manipulate a virtual quadrilateral online.
Tenth graders investigate quadrilaterals. In this geometry lesson, 10th graders investigate the properties of the diagonals of quadrilaterals. The dynamic nature of Cabri provides opportunity for conjecture and verification. The lesson provides examples of real life applications of the properties in construction.
Ninth graders investigate quadrilaterals. In this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas. Additionally, students create various quadrilaterals given three point and the conditions that determine the location of the fourth vertex.
Explore cyclic quadrilaterals and Ptolemy's Theorem. The class uses Cabri to investigate the lengths of sides and diagonals of cyclic quadrilaterals. An excellent teacher's guide, sure to help you through your next cyclic quadrilateral instructional activity.
Students investigate properties of quadrilaterals and their angles. In this geometry lesson plan,students identify the different parts of a quadrilateral and its different kinds.
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.
Students apply definitions and theorems to verify special quadrilaterals using coordinate geometry. They apply the slope formula, the midpoint formula, and the distance formula to justify that a given quadrilateral is a parallelogram. Answer Key included.
Students create, classify and sort quadrilaterals. They create several four-sided polygons, then choose their most unique quadrilateral to share with their group.
Students explore certain characteristics of diagonals and the quadrilaterals that are associated with them, using an applet. They begin with diagonals and deduce the type of quadrilateral that surround them.
Young scholars classify quadrilaterals. In this quadrilateral lesson, students identify the characteristics of quadrilaterals. They write their findings in a journal. Young scholars use geoboards to create quadrilaterals from given descriptions.
Students explore the concept of quadrilaterals. For this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles, etc.
Students explore the properties of quadrilaterals. In this properties of quadrilaterals lesson, students are given a quadrilateral and its measurements and must manipulate the quadrilateral to make the diagonal equal to -1. Students use their Ti-Nspire the construct a quadrilateral given certain requirements. Students guess the type of quadrilateral given a picture and measurements.
Students identify types of quadrilaterals given diagonals. In this identifying types of quadrilaterals given diagonals lesson, students use knowledge of diagonal relationships to identify the type of quadrilateral. Students use a program on the computer that illustrates quadrilateral relationships to help identify the unknown quadrilaterals.
