A key to achieving widespread IT fluency is integrating computing concepts into the K-12 curriculum. We developed a series
of hands-on exercises that use simple, familiar props as metaphors for complex computing concepts. These exercises can
be integrated into the existing curriculum or used as part of a computer science curriculum. These exercises formed the
basis of two professional development courses for teachers taught in July 2004. Once the teachers became comfortable with
the concepts they began to make connections between these concepts and their curriculum. The teachers were amazed at
how much they learned and also surprised to find so many connections between computing and their curriculum.
