CG123 Generating and graphing lists of random numbers
This short video shows how to populate a list with (pseudo) random numbers, simulating the rolling of a six-sided die many times, as well as how to graph this output, using the Statistics app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
CG124 Investigating the sums of random numbers
This short video shows how to generate and sum two lists of (pseudo) random numbers, simulating the rolling of two six-sided dice many times, as well as how to graph this output, using the Statistics app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
Describing change (9860)
This replacement unit introduces algebraic models (linear and simple exponential) to describe change in the world around us. The fitting of models to bivariate data is approached via the underlying properties of constant additive or multiplicative change. The unit contains a wealth of data drawn from a range of aspects of the modern world. Extensive notes are provided on the use of 9860 technology. All of unit’s data is provided it g1m files, ready for file transfer.
CG151 Displaying numbers in different ways
This short video shows you how to change the setting of a CASIO fx-CG series graphics calculator so that numerical values are displayed in different ways.CG20 AU and CG50 AU versions are presented.
Optimisation (9860)
When studying quadratic functions/calculus, do too many of your students find ‘optimisation questions’ hard? Have you ever wondered why? The booklet you can download here is the unit of work that supports the ideas presented in a number of workshops during 2011 and 2012 that outlined why students find the ideas hard. Basically, traditional teaching-and-doing approaches fail to focus on what is really happening: the measurement on one dimension and the subsequent calculation of other dimensions. Also, algebraic simplification turns out to be the devil – the patterns in the symbols are lost and so generalisation is not ‘seen’! The approach in the booklet supports the idea of each student developing a calculation and then comparing and contrasting to it other’s calculations – it is in this that the symbolic patterns appear and the generalisation literally reveals itself.
CG131 Calculating the value of a derivative
This short video shows how to determine a derivative value, i.e. the value of a derivative function for a given x value, using the Run.Mat app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.

CGF11 Transferring Memory Content
This short video shows you how to transfer memory content between the Main and Storage Memory of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
The wind in your sails (9860)
This is a replacement unit to facilitate the teaching and learning of right-angle triangle trigonometry. The students begin by ‘learning’ how to sail a boat and then engage with various aspects of sailing and as a result learn about the fundamental trigonometric ratios. The unit comes with pre-made 9860 Geometry files that enable the students to sail virtual boats, collect data on their sailing and through this learn about trigonometric ratios. The unit includes traditional learning and problems as well as some not so traditional learning.
