Bubble Geometry Have you ever seen a square bubble? Experiment with bubbles. Create bubble wands out of found objects (straws, pipe cleaners, strawberry baskets and coathangers) and have your own bubble festival. How can you catch a bubble? The secret is the soap solution. Try catching a bubble with a dry hand versus a wet hand. Which lasts longer? This activity is included in the Shapes cluster developed with K-2 teachers at the Ross School in San Franc ...

Native American Geometry DESIGNS The Design Section is a playground that exercises visual/mental creativity and behavioral precision. Once the basics are grasped, it is necessary to explore a range of options. This is where the geometry begins to be understood as a spatial language. It is here that many symbols of Native and Historic America and from around the world will be linked to specific polygons. These symbols can be found in street signs (i.e. Stop, Yield) and in the corporate l ...

PerimeterTerms and Conditions For Use | Recommend This Lesson! The perimeter of a polygon is the distance around the outside of the polygon. A polygon is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units. To help us make this distinction, look at our picture of a rectangular backyard. The yard is 2-dimensional: it has a length and a width. The amount of fence needed to enclose the backyard (perimeter) is 1-dimensional. The perimeter of this yard i ...

A tangram is a geometric puzzle with 7 pieces (5 triangles, 1 square, and 1 Parallelogram) that are arranged to create images of various objects. This ancient game, which originated in China, has been enjoyed by many American children throughout the years. Print out the tangram grid. Cut along the lines to form the tangram pieces. Click on the images below for the solution. You can also print out a sheet of solutions.

Integration This unit integrates math with subjects such as language arts and arts education. Throughout our activities we have asked the students to respond to the concepts of tessellations. They will write definitions and assess how well their groups worked together. In addition, we have exposed the students to tessellations in the environment, including interior design. If one can locate some prints by M.C. Escher, students will see how their topic can become a famous art form. As a ...
