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 aids the modeling (with full worked solutions) of calculating area and perimeter of sectors and segments including undoing these formulas to find a missing angle or radius. Please see the video for how the use the teaching aid. I have also included two differentiated worksheets. One for sector area and one for arc length/perimeter. 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 the modeling (with full worked solutions) of using length area and volume scale factors to find missing values. Please see the video for how the use the teaching aid. I have also included two differentiated worksheets (one for lengths and areas and one for length, area and volumes) and a scafolding sheet to support students. 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 creates and solves two sets of linear simultaneous equations dynamically. Drag the vertical slider to reveal the working.
