This uses Geogebra to investigate the rules of parallel lines. The geogebra file has been set up to allow learners to simply check the angles on and off to answer the questions and does not require any technical knowledge. I have included the worksheet that I use as well as a download of the geogebra file and the work sheet has the link to the online geogebra file as well. http://bit.ly/GeoParallel If you prefer an interactive version that allows learners to submit their answers you can use this web page. http://bit.ly/Geogebra_ParallelLines

A homework or worksheet sheet on sample space diagrams. Addition only but exploring the link between sample space with some thinking questions and forming a hypothesis to the sum of opposite sides on a dice. I have also included a spreadsheet. The spreadsheet has editable elements givings sides to create sample space diagrams for addition and multiplication for sides up to 20. It will also output the probability for chosen amounts. Another tab shows the distribution graphically. This could be sent to the learners for them to explore in a lesson or used to support the homework/worksheet.
