Abstract
In most introductory algebra classrooms of the world the highest priorities seem to be algorithms (learning and practicing them) like adding like terms, expanding brackets and so on. During this tutorial you will experience an alternative to this. It does not downplay the importance of said algorithms, but builds a foundation on which they can be built successfully. This approach has the students asking for the algorithms!
The priority in this case is to develop the ability to work algebraically and to develop algebraic sense through engaging in some delightful but simple problems that all students can cope with. The approach employs a revolutionary use of a Computer Algebra System (CAS) as well as use of an interactive geometry system (IGS) and is part of a pilot project being run in NZ schools.
While a variety of electronic technologies can be used, during the session we will use the CAS and IGS on the Casio ClassPad 300.
