Pattern Blocks and other manipulatives from Dale Seymour Publications, 1997
Secondary Mathematics and Science Catalog. Algebra tiles are on page 10,
Pattern Blocks are on page 39. Their toll-free number is 1-800-872-1100.

What are Penrose Tiles and how are they used? >>

Martha-

AHA!!! An excuse to get you to my website!!! 8-) To find out what Penrose
tile are you can pop directly to that page of Karen's Cool Math Site!!!
They
are tiles that tessellate a plane forever and ever and NEVER repeat the
pattern!!

Checked Dale S.... No luck that I recall.

I can only add (from the information gleaned from Karen's site) that the
Penrose tile tessellation exhibits an odd, semi-fivefold nature-- it tends to
produce localized fivefold symmetries.
