An interactive geogebra applet that generates differentiated questions and models how to combine ratios using equivalent ratios. Fully interactive presentation. The geogebra applet is attached but if you don’t have it installed then the web link is also attached so you can use the applet in a web browser.

Model how to calculate the area of a trapezium using this interactive geogebra applet to dynamically convert it into a prallelogram (rotate using the blue dot). Generate new problems on demand and show/hide the lengths by clicking on them. Show/hide the area/perimeter to reveal the solutions. No need for 1/2(a+b)h with this visual prompt! You can open this using geogebra but if you don’t want to install it you can also use it in a normal web browser using the link included.

An interactive geogebra applet to aid modelling of transforming functions. ==> Transform any user-defined function using the ‘add transformation’ buttons and the input/output sliders. The function transforms dynamically as the user changes the input/output. ==> Assess you students understanding by generating random transformations and reveal the function. ==> Add multiple compound transformations (in the correct order!) by keep clicking ‘add transformation’. This is usefult with A-level teaching. If you have geogebra installed on your machine please download the .gbb file. I have also attached a web link if you want to use this resource through your web browser instead of installing geogebra.

An interactive geogebra applet that calculate the area under any user defined curve using integration and using the trapezium rule. Also calculates the percentage error. If you have geogebra installed then please download the .ggb file. If not please use the attached web link to use this applet in a web browser.
