Hands-On Geometry Class

The math classes are all hands-on based enrichment classes based on the inquiry. Students will perform math activities of different topics. Topics may include making tessellations, making a measurement picture, making basic polyhedral shapes, and geodesic dome creation. Optional activities include solving Sudoku puzzles, making and solving your own tangrams, and transformation of the plane problems.

Making Tessellations

Learn about wallpaper patterns and the difference between regular, semiregular, demi regular, and irregular tessellations. Then make stained glass windows using different tessellations and color patterns. Learn about M.C. Escher, a famous artist known for tessellations. It is best to use a tool called “Tessellation Tracers” to make accurate polygons.

Geo-Pictures

In this lesson, students use a ruler and protector to draw pictures. The first thirty minutes will involve how to measure with a protractor and how to accurately use a ruler. While this is a review for most students, skills are developed to increase accuracy through the activity. While there are a variety of picture directions in order to accommodate individual differences, students are expected to know basic terminology about measurement and figures. One example is shown here.

Drawing Directions:

From the top left corner of the paper, measure 5 inches down and 5 inches to the right and draw a point.
Use this point to make the center of a circle with a radius of 3 inches.
From the bottom left corner of the paper, go up 3 inches and draw a line across the paper 3 inches long.
Turn left 90 degrees and draw a vertical line 4 inches long.
Turn right 45 degrees. Draw a line 7 inches long.
Turn right 90 degrees and draw a line 4 inches long.

POLYHEDRA PROJECTS

Using the website below, students pick a template to make a make a three-dimensional model based on their interest and ability. The project is a ninety-minute activity.

The Geodesic Dome

We will be building a 2V dome called a Hex-a-Pent dome. It is made from six hexgonal panels called isoscocaps. It is a very strong structure made from PVC pipe, wire, tape and construction paper. The size of the pipe controls how big the structure is.
