3D model description

####Marble Rings, Hungarian Rings, Marble Fun

Marbles can be used in various ways to make geometric patterns and invite student participation in a math class. In this design, two circles are interlocked with each other to form two overlapping tracks, which are sometimes known as Hungarian Rings or Devil's Circles.

Marbles can be pushed into the tracks through the two opening in the middle. They will roll around. There are many questions one can ask, if so desired, especially when multiple colors are used; otherwise, it is a lot of fun just to spin them around and watch the chaos. Once they are pushed in, they are not easy to shake out of the tracks.

Four Sizes

There are four marble sizes included (12mm, 14mm, 16mm, 18mm). The openings in the middle vary with the marble sizes. An example (16mm marble) is shown in the figures. There is also a 1mm tolerance to allow the marbles to roll around. Marbles come in irregular sizes; do please try them out.

STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.

When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides:
