First of all, few seem
to realise that this is feasible (so a triangle is
really a net of a pyramid?) but earlier finishers can
also create their own question/answer combinations to go
on the blank parts of the triangle that will be stuck
step I wonder if I can make my own ones with
questions/answers on every side of the triangles so that
it will make a complete tetrahedron. Will pupils be
able to work it out?
