problem can be found in the
Notes to More Magic Potting Sheds

This activity offers students the opportunity to explore a new
environment and challenges them to use some deductive reasoning.
The problem can be tackled on paper but access to the interactivity
will speed up the process of exploring different
possibilities.

It is important to have paper available for students to record
the results of the different trials.
