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 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.

A PowerPoint modelling how to construct a triangle given two side lengths and one angle. Includes non-unique triangles (SSA).

An interactive geogebra applet that models the how to calculate using speed, distance and time (with and without a calculator). 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 generates examples (carrying out and describing) of all geometric transformations including… ==>reflections ==>translations ==>enlargements (positive and negative SF) ==>rotations Use with an interactive whiteboard to practice carrying out and describing transformations. Use the nagivation buttons to generate examples and carry out the transformation by dragging the green slider (see video for usage). You either need geogebra installed on your machine or use the web link (attached) to use the resource within a web browser without the need to install geogebra. UPDATED: Differentiated worksheets also included.

An interactive geogebra applet that aids modeling plotting graphs using substitution. Watch the video for demonstration on how to use. A range of differentiated worksheets are 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 enables the user to input their own inequalities and objective functions in any linear programming problem and solve it graphically. Add an inequality/objective function 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. 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. I have also attached a worksheet i have used with my own A-level students to practice using this technique. 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.

A differentiated interactive geogebra applet that aids the modelling (with solutions) of route planning with algebraic vectors including interleaved with ratio problems as seen is Edexcel 1MA1. Please see the video for how the use this teaching aid. I have also included four 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 allows the teacher (or students on ipads/in computer room if uploaded onto geogebra website) to create right angle triangles using a set number of standard squares. Students can record their trials and try to spot any relationships between the size of the squares that work. An accompanying worksheet and lesson plan to match. You need geogebra installed (free) or use the web applet that does not require geogebra to be installed.
