A Visit With Master Artists and Teachers – Michael LaFosse and Richard Alexander

2018-11-23T19:14:08+00:00

A local museum is hosting an exhibit entitled "Origami in the Garden" until March of 2019.  It's a fantastic series of metal sculptures based on origami designs scattered throughout the gardens of the museum.    As part of the exhibit's kick-off activities, Michael LaFosse and Richard Alexander, master origamists, were invited to visit local schools and to teach workshops at the Botanic Garden.  I was fortunate enough to be able to attend one of their workshops.  It was great! Using giant squares of paper and the wall as their flat surface, Michael and Richard showed a group of about 25 how [...]

Paper Quilting – Colored Paper, Creativity, Geometry, and a Little History Mixed In

2017-03-08T19:27:53+00:00

    It's cold outside (OK, in some parts of the country it is)- the time of the year when people think about curling up under a warm quilt with a cup of hot cocoa and a good book, unless you're a kid, of course.  Sitting still under a warm blanket is really hard when you're young and full of the cabin fever wiggles. But what about reading a great picture book about quilts, enjoying the wonderful illustrations, then creating your own quilt squares out of paper?  There are plenty of books to choose from.  Not too long ago, I did [...]

Poly- What? Learning the language of 3D Geometry

2017-02-04T17:52:03+00:00

    Shapes, shapes, and more shapes.  Circle, triangle, square, rectangle - it all starts of easy enough.  Then it get a bit more complicated when you move from two dimensional to three dimensional - sphere, cylinder, pyramid, cube, prism.  Then, before you know it, your tongue is in a knot, and you're totally confused.  Just what does a decagonal gyroelongated bipyramid, compound of truncated icosahedron and pentakisdodecahedron, or a prolate hectohexecontadihedron look like?  It's all in the name.  The trick is understanding the language of shapes, and a little bit of Greek and Latin.  For help with the Greek and Latin, [...]

Tangrams – Stories, Shapes and Spatial Thinking

2016-02-19T16:03:11+00:00

      Tangrams are possibly among the easiest of puzzles to make, and the among hardest to master.  The traditional tangram is composed of seven pieces - 2 large triangles, a medium sized triangle, 2 small triangles, a square, and a parallelogram - that will fit together into a perfect square, among thousands of other shapes.  The pieces themselves are called tans, while the images created with them are called tangrams.  The challenge of the puzzle is to create various shapes by arranging the pieces so that they touch, but do not overlap.  Patterns can vary from very easy to form [...]
