An interactive geogebra applet that enables the user to graph any number of user defined inequalities on the same set of axes. Add an inequality using the controls and drag the points to the desired co-ordinates to create the boundary line then click up/down to shade the desired inequality. Once all inequalities are added use the show overlap button to real the correct region satisfying all inequalities. 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. 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 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. 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 using 1/2absinC to calculate the area of a non-right angled triangle. Watch the video for demonstration on how to use. 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 solving linear equations by balancing. Watch the video for demonstration on how to use. 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 applying the sine and cosine rules for non-right angled triangles. Generate random missing length or angle questions using the buttons and use the slider to reveal the step-by-step working. 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. Now includes worksheets too!

Models how to evaluate fractional and neagtive powers. Fully interactive and dynamic examples. Please see the video for how to use (note you must enable macros on the start of the PowerPoint for the interactive power counters to work, see video)

An interactive geogebra applet that models the how to calculate average and spread of a data set including… ==> Mean, median, mode and range from a list of numbers ==> Reverse average problem solving ==> Combining mean problems ==> Mean from an ungrouped frequency table ==> Median from an ungrouped frequency table ==> Interquatrile range from an ungrouped frequency table ==> Estimate of the mean from a grouped frequency table ==> Estimate of the median from a grouped frequency table ==> Estimate of the interquartile range from a grouped frequency table The applet generates progressively differentiated examples for modeling with your class. Please see the video for how the use the teaching aid. I have also included a set of differentiated worksheets with solutions. These are also previewed in the video. 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 models the how to proportionally scale up and down including using the unitarty method and non-calculator methods. It then extends to using proportion to compare ‘best buys’ including BOGOF examples. The applet generates progressively differentiated examples for modeling with your class. Please see the video for how the use the teaching aid. I have also included a set of differentiated worksheets with solutions. These are also previewed in the video. 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.

A presentation demonstrating how to construct a triangle given all three sides.

A PowerPoint modelling how to construct a triangle given two angles and a side length.
