ab: Summary: The context of a problem in which a bee on the outside of a
cylindrical jar seeks the shortest route to a drop of honey inside the
jar is used by the author to suggest a practical approach to its
solution. This is an account of a classroom activity that seeks to
solve a relatively complex problem with the help of â€˜customisedâ€™
model. The visualization and understanding required to resolve things
is enabled by the model which, as it is formed from acetate sheet, is
transparent.
