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.
CG515 Changing a graph’s View Window
This short video shows how to change a graph’s View Window, using the Graph app of a CASIO fx-CG series graphics calculator, and discusses some of the advantages and disadvantages of different View Window settings. CG20 AU and CG50 AU versions are presented.
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. 🙂
