The Sphinx sits on top of an iceberg of investigations related to mathematical language, shape and space, tessellations, area, perimeter, patterns, powers, mathematical proof, similar shapes and who knows what else is yet to be discovered.
Until now, teachers and students had to print the shapes from the web, make multiple copies, laminate and then cut out the shapes one by one! But now strong, colourful plastic shapes are economically available.
