Teaching Symmetry In The Elementary Curriculum, Christy Knuchel Apr 2004

Teaching Symmetry In The Elementary Curriculum, Christy Knuchel

The Mathematics Enthusiast

Symmetry is a fundamental part of geometry, nature, and shapes. It creates patterns that help us organize our world conceptually. We see symmetry every day but often don’t realize it. People use concepts of symmetry, including translations, rotations, reflections, and tessellations as part of their careers. Examples of careers that incorporate these ideas are artists, craftspeople, musicians, choreographers, and not to mention, mathematicians.

It is important for students to grasp the concepts of geometry and symmetry while at the elementary level as a means of exposing them to things they see everyday that aren’t obviously related to mathematics but have …

Radius, Diameter, Circumference, Pi, Geometer's Sketchpad, And You!, Scott Edge Apr 2004

Radius, Diameter, Circumference, Pi, Geometer's Sketchpad, And You!, Scott Edge

The Mathematics Enthusiast

I truly believe learning mathematics can be a fun experience for children of all ages. It is up to us, the teachers, to present math as an interesting application. The addition of computers into our ever-changing world has given us an important tool, which can assist us on our journey to teach math in new fun and interesting ways. The Program Geometer’s Sketchpad© is one of many mathematic programs we as teachers can use to better help kids understand different geometric concepts. I would like to use Geometer’s Sketchpad© in my classroom to help teach my students about circles and …

Exploring Perimeter And Area With 4th Graders, Amber Lieberg Winkler Apr 2004

Exploring Perimeter And Area With 4th Graders, Amber Lieberg Winkler

The Mathematics Enthusiast

I am going to teach basic introductory geometry skills to 4th graders using Geometry’s Sketchpad. At this age, children are only beginning to learn about geometry in their math classes, and I would like for the students to understand these basic concepts using technology. This problem is so important for the students to learn early, and learn correctly. These skills will involve finding the area and perimeter of regular polygons, basic skills using Geometry’s Sketchpad, and activities that will apply these introductory concepts; directly correlating within the national geometry standards of mathematics. Children use geometry everyday, even when they don’t …


A Rank Correlation Coefficient Resistant To Outliers, Rudy Gideon, Robert Ashley Hollister Jun 1987

A Rank Correlation Coefficient Resistant To Outliers, Rudy Gideon, Robert Ashley Hollister

Mathematical Sciences Faculty Publications

In this article, a nonparametric correlation coefficient is defined that is based on the principle of maximum deviations. This new correlation coefficient, RgB is easy to compute by hand for small to medium sample sizes. In comparing it with existing correlation coefficients, it was found to be superior in a sampling situation that we call "biased outliers," and hence appears to be more resistant to outliers than the Pearson, Spear- man, and Kendall correlation coefficients. In a correlational study not included in this article of some social data consisting of five variables for each of 51 observations, Rg was compared …
