Logarithms – when adding is multiplying (Classpad)
This unit aims to provide a simple/useful way to thing about logarithms when first meting them.
We use two examples of “hard” to graph data (due to the extreme range in the values) to alert students to the idea of thinking about a number as its power, as opposed to its absolute value.
The rest of the unit aims to establish a way to think about calculating with logarithms that will set a sound foundation for later on and that builds on their knowledge of ‘indices’ from previous years.

Prime Factorisation using the 2nd edition fx-82/100AU PLUS
This short video shows how to find the prime factorisation of an integer, using a Casio fx-82/100AU PLUS. This powerful mathematical representation is then used to determine how many divisors two integers have, as well as their greatest common divisor.

fx-CG50AU
Graphing Calculator
The fx-CG50AU is Casio’s next generation 3D colour graphic model that carries on the tradition of innovation.
The fx-CG50AU hosts the same great features of its predecessor – the fx-CG20AU, but also includes a new 3D graphing function, catalog function and E-CON4 application. It also has 4.5mb of storage memory built-in, the same as the fx-CG20AU. For existing users, the new machine operates the same way, but with improved technology, and faster calculation.
