An interactive geogebra applet that aids modeling calculating the equation of a tangent to a circle. Use the slider to set the centre (differentiated with (0,0) or non (0,0) centres) and generate an example using the button. Please note, GCSE only ever need to consider (0,0) centres but this could be used for A level teaching too with none (0,0) centres. Show the working by clicking on the button and then click each line of working to reveal the next line. A differentiate worksheet is also attched.

A fully interactive geogebra presentation. Generates examples of all circle theorems that can be manipulated dynamically to reinforce that the relationships are always maintained despite how each theorem can appear visually. Modeling of all proofs are also included and differentiated questions can be generated for whole class participation or to create a worksheet of your own. See the attached images for examples and how the controls work. This is an interactive geogebra applet but, if you don’t have geogebra installed (free), I have also included the web link so that you can use this applet in any web browser. I have also included some worksheets I made.

An interactive geogebra applet that generates a quadratic equation that can be solved using a set of simultaneous equations (one quadratic and one linear). Generate new examples and click the question to change into a more complex example (as seen in 1-9 Edexcel papers). Students need to decide on which linear functions to add to the quadratic graph to solve the equation given. Plot the linear function by clicking on it and use the navigation buttons to show the number of solutions and their value. You either need geogebra installed on your machine or use the web link to use the resource within a web browser without the need to install geogebra.
