Flow – Ideas that underpin Differential Calculus
Presented here is a tried and proven three to five lesson sequence that begins with an engaging real-world context and grows students from the idea of average rate of change to instantaneous rate of change.
It is accessible to any student who has an understanding of average and gradient.
In this collection of resources you will find: a) a three-part introductory video (I, IIa and IIb), which structures the sequence of learning, b) two support video that shows “how to” do the technical stuff on the CG 20 AU.
Exponential and trigonometric functions
A selection of documents that share some nice ideas about exponential functions, trigonometric functions and a lovely context where both concepts come together.

CGA11 Solving a system of simultaneous equations
This short video shows how to solve a system of linear simultaneous equations using the Equation app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
CG223 Fitting a regression model to bivariate data
This short video shows how to generate a regression model of “best fit” for bivariate data via a scatterplot drawn using the Statistics app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
CGA31 Solving an equation
This short video shows how to solve ‘any’ equation using the numerical solver in the Equation app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented. Changing the ‘seed’ to obtain an alternative solution, and the graphical representation of multiple solutions, is included.
CGA32 Solving for unknowns in formulae
This short video shows how to find the value of an unknown, via the substitution of known values into a formula and the use of the numerical Solver in the Equation app of a CASIO fx-CG series graphics calculator. CG20 AU and CG50 AU versions presented.
