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 working with algebraic expressions. Use the sliders to set the type and difficulty of question. click the hint button to provide scaffolded working (see video demo for 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 modelling of both vector addition and subtraction with algebraic vectors and using parallel vectors to define quadrilaterals. Please see the video for how the use the teaching aid. I have also included a worksheet of similar questions. 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 of solving linear/non-linear simultaneous equations. Use the sliders to select the example type from… linear/quadratic linear/circle quadratic/quadratic circle/quadratic …and generate an example using the black button. All examples have rational roots so the quadratic formula will not be needed. Click the substitute button to reveal the first line of modeling/working and then click each line of working to reveal the next. The graphs are also shown to reinforce the graphical link of the algebraic process. 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. I have attached two versions. One where the circle are limited to (0,0) centers as in GCSE study and one where it is not as in A-level study.

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.
