Simplex & The Science Of Burger Making
The simplex algorithm, sometimes dubbed the world’s most powerful, sits at the heart of linear programming. Classically the subject of tertiary-level study, Dantzig’s simplex algorithm can be used to solve important problems like how to make a ‘better’ burger patty. …

As Big As Can Be
The introductory videos introduce students to a complete unit of work, a study of quadratic functions. The unit starts with a geometric optimisation problem (paper folding) that prompts students to ask the question “is that as big as can be?” …

CG115 Performing trigonometric calculations
This short video shows how to perform trigonometric calculations using the Run-Matrix app of a CASIO fx-CG series graphics calculator in order to solve simple trigonometric equations. CG20 AU and CG50 AU versions are presented.
Generosity – an approach to fractions and percentages.
This unit uses the context of generosity to introduce a need to have a fractional way of thinking about something.
It develops a way of thinking about fractions – the for-every idea – that is the elusive multiplicative model.
Developed over about 5 years, this approach has been tried and seems to work. 🙂

CGA21 Finding the roots of polynomials
This short video shows how to find the roots of a polynomial function up to degree 6, using the Equation app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
CGC11 Calculating loan repayments
This short video shows how to calculate loan repayments on a reducing balance, compound interest loan using the Financial app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
CG601 Drawing a ‘dynamic’ graph
This short video shows how to draw an animated ‘dynamic’ graph showing the effect of changing a parameter upon the graph of a function, using the Dyna Graph app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented. In particular, the effect of changing the gradient value “m” in a linear function of the form y=mx+c is addressed.
CG514 Finding x and y values using a graph
This short video shows how to determine a function’s x and y values from its graph, using the Graph app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
