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 calculate the discriminant and links this to the graphical representation. Includes reverse discriminant to find a range of k as in A level examination questions. I have also included a differentiated worksheet for independent practice. Please watch the video for how to use the geogebra applet and for a preview of the worksheet. 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.

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 enables the user to model how to graph inequalities in two variables (i.e. shading regions). Please see the video to see how to use. I have also included two differentiated worksheets. One for drawing/shading regions and one for identifying regions. Answers are 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 a web browser.

An interactive geogebra applet that aids the modeling of drawing and interpreting histograms. Includes equal class widths (normal bar charts) and unqual class widths (histograms). Please see the video for how the use the teaching aid. I have also included two scaffolded worksheets. One for reading and interpreting histograms and one for estimating quartiles and percentiles as seen in A-Level and GCSE specs. 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 work with two-way tables including… ==> Completing two-way tables ==> Solving worded problems using two way tables ==> Writing proportions from two way tables ==> Problem solving with two-way tables ==> Testing for independence in two-way tables 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 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 demonstrates the similarities and differences between frequency bar charts and pie charts (often confused by students). Please see the video for how the use the teaching aid. I have also included a differentiated worksheet. 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 to use with your class to aid modelling of… ==> Writing numbers as a product of primes using trees (prime factorisations) ==> Using a product of primes to help root numbers without a calculator ==> Using a product of primes to calculate the LCM or HCF ==> Using a product of primes to calculate the LCM or HCF but in worded contexts 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.
