This is a lengthy overview PowerPoint that defines, explains, shows examples, and has practice problems about points, lines and planes.  The class will need to write many notes and there is an example of how to set up in the Cornell...

Young environmentally conscious mathematicians solve a variety of problems related to the central theme of uncovering illegal logging activities. They determine a base camp based on given constraints, investigate logging activities and...

High schoolers create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground...

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

Students build replicas about nature and sports. In this geometry lesson plan, students build 3D replicas of nature and sports objects in teams.

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson plan, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new...

Students describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Students recognize and name two-dimensional and three-dimensional geometric figures. One group of students will extend the study of polygons to quadrilaterals while another group of students will extend the study of polygons to...

In this interactive activity, students review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations....

Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...

Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

Learners discuss figures with various numbers of sides.  In this geometry lesson plan, students are read The Greedy Triangle by Marilyn Burns, they participate in a class discussion of many sided figures and are introduced to the...

Learners complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.

Students follow directions to make a stained glass window design of regular and irregular polygons with specific geometric elements. In this geometry lesson plan, students also analyze other classmate's designs.

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...
