Students explore solar energy, why we use it and how we use it.  In this renewable energy lesson students compare active and solar techniques.

Students calculate the sum of the angles of a polygon. In this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.

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

Experiment with optical resolution using an inquiry-based lesson plan. Young researchers calculate fellow classmates' optical resolutions. They apply the information to understand the inner workings of optical instruments.

Learners explore the relationship between how big a side of a triangle is and how big its opposite angle is by creating triangles using an interactive website.

Students explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles outside...

Students construct a set of tangrams. In this geometry lesson, students read the book, Grandfather Tang's Story and retell the story using tangrams. Students construct their own set of tangrams using the included worksheets.

Fourth graders use computer drawing tools to create a house of geometric shapes.

Second graders identify different polygons and their attributes. In this geometry instructional activity, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students explore the concept of the corner problem. In this corner problem instructional activity, students use the TI-NSpire to determine the maximum length a rod can be and still pass horizontally around a corner. Students use similar...

Students design and build their own solar cooker. In this math instructional activity, students determine the relationship between the angles of the sun, reflection and cooking time of the solar cooker. They test their project,...

Students differentiate between similar and congruent polygons. In this geometry lesson plan, students define the theorems and reasons for polygons similarity and congruence. They are given pictures and patterns to differentiate and...

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

Seventh graders investigate geometric shapes using tessellations. In this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Students investigate the concept of two dimensional polygons. They complete a vocabulary chart with the teacher or in independently. Students are shown various polygons in order to classify them and then asked to draw one of them from...

Students discover which regular polygons can be used to tile a plane.

Second graders Make, name and describe, using their own language and the language of geometry, everyday shapes and objects. They create and talk about geometric patterns which repeat (show translation), or which have rotational or...

Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.

Students experiment and analyze triangulation to assess degrees of combined angles, predict polygons that tessellate as well as extending of shapes to create tessellations. They explore the concept of why some polygons tessellate when...

Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...

Students use shape puppets to review geometry content. They take turns singing songs, reading students poems, reciting class bulletin board notes and choral poems. They prepare for their summative assessments through play and interview...

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Students build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by trial...
