Locally in Coventry and Warwickshire we have developed the following
Challenges In A Box for school teachers to use to assist in educating pupils of
various ages. We are keen to have feedback and new ideas for these challenges.
Each challenge has visual aids and, where relevant, pupil guides and
teacher guides.
Challenges In A Box are copyright © Derrick Willer.
However you are free to copy for use in schools and for instructing
children of school age and for use by children of school age. Please feedback
to: Derrick Willer, dw@dwiller.com
However, I suggest that you give a small donation
(e.g. £25, $30) to the Memusi Schools in remote Kenya
so that they can install electricity and then get computers.
