## 10 to 1: My Top Ten Maths Lessons with an IWB

From this web page, you can download the flipchart for this workshop plus all supporting resources. The flipchart and most of the accompanying resources are in the zip file. The Celebrity Ages files were too large for the zip file, so are available as separate files.

You can also download the flipchart for the workshop "Ten Terrific Tips for Teaching with (Digital) Technology".

## Transformations of the Trig Functions with Geogebra

This Geogebra file shows dynamically how the graphs of the sine, cosine and tangent functions change as the parameters in their equations are changed. Thanks to Greg Bland for sharing this very visual activity.

Geogebra is a powerful FREE dynamic geometry program. You can download it from

## Projectile Motion with Geogebra

This is a very cool Geogebra file that shows the vectors involved in projectile motion. Thanks to Greg Bland for sharing this file. Three thumbs up!

## Vectors with Geogebra

This zip file contains two Geogebra files that dynamically illustrate vector concepts - one that shows the forces on an object on an inclined plane and one that shows the resultant of three forces acting at a point. Thanks to Greg Bland for sharing these. Both are excellent teaching aids - 3 thumbs up!

## Conics with Geogebra

A collection of four Geogebra files from Greg Bland that will help students understand conics.

## Sketch-up Files: Volume and Cross-Sections

Bill Newell has kindly shared some Google Sketch-up files on volume and cross-sections that he has created.

The files have been zipped, so you will need to unzip them before you can your them.

## Learning by Simulations - Cubic Splines

Cubic splines are cubic functions which are used in applications such as automobile design. The basic idea is to fit cubic polynomials between two neighboring data points while ensuring that there are "smooth" first and second derivatives at the data points. The program available from this website as a zip file is a useful tool for investigating cubic splines.

## Learning by Simulations - Differential Calculus

Distance, time and velocity are an ideal means to understand the concept of derivation. By reducing the time interval until it becomes zero, the average velocity approaches the instantaneos velocity, which is equal to the first derivative of the distance (with respect to time). This is available as a zip file that can be downloaded.

## Learning by Simulations - Riemann Sum

Choose a function and see the effect on the Riemann sum when you change the slice width. The file itself can be downloaded and installed on your computer or network.

## Bill Newell's Autograph Files for Calculus

Bill Newell has kindly agreed to share some Autograph files that he has created for teaching calculus. To access the files, you will have to unzip them first.
