Geogebra is a dynamic mathematics software and I have used it previously to create drawings and diagrams for my lesson plans.  But inspired by this post with a geogebra widget on parts of a circle, I spent a little bit of time exploring the geogebra wiki and realised how easy it is to create simple interactive worksheets.  I recently taught parts of a circle to a Year 8 class whilst on prac.  I gave out small sheets of paper with a circle drawn on it so students could draw in and label the various parts of the circle as we went through it together on the whiteboard.  Using a widget like the one included in the post above, the students could have played with it and taught themselves. 

I knocked up an interactive worksheet in just a few minutes (literally) that could be used by students to explore Pythagoras’ thorem.  (I would attach the file here if I could figure out how . I can’t even manage to get a screenshot in). This has definitely motivated me to play around with Geogebra a bit more and extend my current capabilities.
