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.

An interactive geogebra applet that enables the user to input their own inequalities and objective functions in any linear programming problem and solve it graphically.

Find all points of intersections via the click of a button and drag the objective function to leave a trace and revel the optimum vertex (i.e. the ruler method referred to in many A level texts). Auto zoom and fitting for easy class use and to model a clear solution. Some pre-defined questions are included if you want to use them to model with.

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.

I have also included some worksheets I made.

An interactive geogebra applet that aids modeling of drawing Venn diagrams from set notation (as seen in Edexcel 1MA1). Use buttons to generate a new question and click on each set to show the shading on the Venn diagram. Start when the most colours overlap and work back from there. A differentiated worksheet also included. 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 any web browser.

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. 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 any web browser.

An interactive geogebra applet that aids modeling drawing and interpreting pie charts. Click the black buttons to select either drawing or interpreting and genreate a problme by clicking ‘new’. Click on the table to reveal the angles and then click ‘show protractor’ to model using the protractor to mark the angles (the prompts will help you use this). Once the last angle has been draw, it will automatically label the pie chart. A differentiate worksheet is also attched.
