it takes a while for students to find all 12 usually

one purpose is to provide tiles to tessellate, in a variety of different ways

rather than just fitting shapes together, without any regularity, it's important that students appreciate that they should be able to detect 'stripes' in their tessellations
after all, all tessellations are actually tesselations of parallelograms
(seen by connecting corresponding corners)
