Students make a quilt. In this geometry lesson, students discuss patchwork quilts and learn some different geometric shapes and patterns that are commonly used. Students explore designs with triangles and squares and then make their own...

Students study geometric images and polyhedrons. In this geometry instructional activity, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a...

Students explore the concept of fractal patterns. In this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

Students design a collage of pictures for a yearbook that make a shape. They determine the area of the shape and the price of putting the collage in the yearbook.

Students, as a final project, draw a picture of their ideal neighborhood on a sunny day. In addition to the sun, their drawings include homes, trees, streets, and selected objects. Each object in their drawing has a written description...

Students analyze how the parts of a system go together and how these parts depend on each other. They comprehend the forces in terms of strength and direction. Students observe, measure and describe weather indicators.

Young scholars explore points, lines and planes as it relates to geometry. In this geometry lesson, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Fifth graders use the Internet to learn about translations, reflections and rotations. Students access the Transmographer program on the Internet, where they practice what they have learned. Students also complete a worksheet.

Students solve problems with percents, decimals and fractions. In this algebra instructional activity, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

Students reflect, rotate, translate, and dilate figures in the Cartesian coordinate plane using grid paper and dot paper. They use transformations (i.e., reflections, translations, rotations, and dilations) to describe geometric patterns...

Get the definition and properties of a polygon. Then explore such topics as: 1) types of polygon 2) area 3) Perimeter 4) angles associated with polygons and 5) names of polygons.

This lesson focuses on polygons; a polygon is a closed, flat shape that has only straight sides. Polygons can have any number of sides and angles, but the sides cannot be curved.

The properties of the four different types of polygons--pentagons, hexagons, heptagons, and octagons--are discussed here. Some practice questions are also given to test your knowledge.

Students can practice classifying polygons in a series of self-check exercises and timed learning games.

Students can practice identifying polygons through a series of self-check exercises and timed learning games.

Looks at the lines of symmetry in different types of polygons. Includes ten practice questions. Each question is accompanied by an explanation of the answer.

A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

Identify the polygon based on clues in this online game.

This lesson explores the characteristics of various types of polygons. It includes two PowerPoint presentations that test students' understanding by grouping polygons in the correct categories.

[Free Registration/Login may be required to access all resource tools.] Here you will explore displays of data using bar charts, histograms, pie charts and boxplots, and learn about the differences and similarities between them and how...

[Free Registration/Login may be required to access all resource tools.] This study guide focuses on polygons: convex vs concave, interior and exterior angles, and basic terminology for common polygons.

Classify shapes based on pictures or attributes, such as angle types and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A complete reference guide to polygons. It provides definitions, examples, and an interactive activity that enhances further explanation. Includes links to related topics.
