High schoolers establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

In this test for parallelograms learning exercise, learners solve 15 short answer problems. Students determine if a given sketch is a parallelogram given angle measures and/or side lengths. Learners use knowledge of parallelograms to...

Students explore differents types of triangles and quadriaterals. In this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference between...

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...

Students create, classify and sort quadrilaterals. They create several four-sided polygons, then choose their most unique quadrilateral to share with their group.

In this quadrilaterals worksheet, students find the missing measurements of side lengths and angles in isosceles trapezoids and kites.

In this geometry worksheet, 10th graders match basic vocabulary words relating to angles, circles, quadrilaterals, and transformations in a drag and drop game format.  The one page interactive worksheet contains twenty matching...

In this geometry worksheet, students fill out three columns with thoughts on quadrilaterals. They write what they know, what the want to know and what they have learned.

In this quadrilaterals activity, 10th graders solve and complete 10 different problems that include various types of quadrilaterals to identify. First, they find the value for each variable in the illustrated quadrilateral. Then,...

In this classifying shapes using Venn diagrams worksheet, students draw examples of isosceles, right, and equilateral triangles in the proper sections of the first graphic organizer. They draw polygons, both regular and quadrilaterals,...

Fourth graders discuss the various attributes of quadrilaterals. In groups, they use the attributes to sort quadrilaterals into different classes and a hierarchy. They review the new vocabulary and attributes with a partner to end the...

Tenth graders investigate the geometric concept of quadrilaterals. They are given a set of shapes and asked to sort the quadrilaterals from the others. Then working in pairs they discuss the characteristics and write down the description...

Fourth graders explain the characteristics of quadrilaterals and describe, identify and analyze characteristics and properties of geometric shapes.

In this quadrilaterals and polygons learning exercise, students solve the problems using quadrilaterals and other polygons. Students solve six problems.

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.
