Students solve real life scenarios using math. In this geometry instructional activity, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.

Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.

Students define properties of polygons. In this geometry lesson, students differentiate between similar and congruent polygons. They identify and use the properties of solids to solve problems.

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

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.

This lesson introduces students to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.

In this angle worksheet, students answer forty mental math questions divided into four problem sets.  These problems require students to remember angle facts and so simple calculations mentally.

Students think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is practiced.

Students explore the concept of fractals. In this fractal lesson, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Young scholars, after researching the history and foundation of Renaissance rose windows, access ArtEmboss to create an original window design. They employ a basic metalworking technique utilizing a soft metal. The design created...

Students classify, flip, slide, and turn a quantity of quadrilaterals.

Middle and high schoolers identify and analyze fractals and research information using the Internet to locate information about them. They look at fractals in relation to nature and other real world situations. Pupils create several...

Fifth graders study English reading and writing skills as they participate in exciting interdisciplinary hands-on activities using a basal reading series.

Young scholars discuss how color construct meaning in art. They will demonstrate a technical knowledge and creative use of formal elements and principals of design. Students then discuss the way their selection of color contributed to...
