Geoboards are widely used in early math to help students make sense of geometric shapes and their algebraic properties such as the Pythagorean Theorem. They can be used for a variety of topics or just for fun. The geoboard files here are designed for K-12 teachers, with reinforced pins and hollow spaces underneath to reduce warping and for easy removal. Each pin has three positions to allow multiple layers of rubber band construction.
There are three different dimensions and two styles. They are no larger than 140mm x 140mm x 32mm. I don’t see any point in making a 3 x 3 board. Large ones are certainly possible if necessary. There is an isometric (5x5) one for special needs; there is also a circular one for playing with angles and fractions. Everything is made using Autodesk Fusion 360™. You would need a bag of thin (and colorful, preferably) rubber bands to use the geoboards.
Regarding printing, PLA is fine at 0.20mm, without no support or raft.
Please use a thin spatula to remove because of its size.
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: http://www.nsta.org/safety/.
