Fifth graders solve problems while examining a variety of isosceles triangles.  In this isosceles triangle lesson, 5th graders examine shapes to find their characteristics.  Students pay particular attention to the...

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Middle schoolers identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Middle schoolers cut shapes out of...

Students create their own ancient civilizations based off of topographical maps of Egypt, Mesopotamia, the Indus Valley, and the Yellow River. In this social studies lesson, students are assigned one topographical map to use to create...

Students explore the concept of quadrilaterals. In 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,...

Students study triangles. In this triangle lesson plan, students compare and classify triangles while milling to music. Students will also trade triangles so they can match up with other similar triangles. Triangles are provided.

Have your class review how to identify right angles. Learners identify right angles, and then write the number of angles found in each shape.

Rocks hold evidence of Earth's past. A three-step guide describes the process of creating a rock collection. It provides a data collection sheet to make notes about each sample.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Fifth graders classify triangles. For this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Learners explore the concept of the binomial system of nomenclature for classifying organisms. Students travel on a field trip to observe organisms displayed and their common names. Learners complete several classroom activities and...

In this bonding worksheet, students read about the types of bonds that hold compounds together. They are given fifteen common materials and they identify the types of bonds that hold each together.

Students identify triangles in the real world and construct their own triangle using drinking straws. They explore abstract triangles and find additional geometric shapes such as trapezoids. Students discuss similar shapes and examine...

Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Learners build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students calculate the area of a parallelogram. In this geometry activity, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.

Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.

Fifth graders explore the various properties of earth and rocks. They play "Twenty Questions" with the teacher, and analyze a rock using a magnifying glass. They record their rock observations and list the differences between the wet...

Students design a twenty-first century book cover based on the concepts and designs of the eighteenth century.

Pupils define properties of rectangular prisms. In this geometry instructional activity, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.
