Interactive geometry has been around for quite some time, yet there are relatively few resources specifically designed to help teach everyday maths topics to students aged 11 to 18 using graphic calculators and handhelds. This website is attempting to address this shortfall.
It appeared to me that too many interactive geometry resources on the internet seem to focus on the invariant properties of triangles and their altitudes, medians and angle bisectors. I am of the opinion that interactive geometry can be used to help teach many more maths topics than this!
A whole new approach to teaching maths can be facilitated using CabriJr and Nspire that uses 'multiple representation' as its core ingredient. Allowing students to see the same problem geometrically, graphically, numerically and algebraically offers them greater levels of accessibility and comprehension.
In addition, I think that CabriJr is a nice, manageable
environment for users who are new to interactive geometry to develop their
skills and gain an awareness of all that it can do. Users could then progress
onto using more sophisticated versions of similar software, either onto
a desktop computer, with all the colour and screen resolution benefits
that they may offer, or onto the TI-Nspire with its revolutionary operating
Any worksheets were created using Microsoft Word and converted
to pdf format using Adobe
