Students run a simulation using M&M'S® whereby they eat each of the M&M'S with the M facing upward. Each time approximately half the remaining M&M'S get consumed. The result is exponential decay. A truly memorable and satisfying mathematics investigation!

Watch Activity Tutorial
Understanding transformations looks at how points are translated and dilated (towards and away from the axis) and what this means for the equation. The new point tool makes this very intuitive. The extension content naturally blends this approach into matrices and helps students understand rather than blindly applying rules.

Watch Activity Context
In 1968 Bob Beamon's world record long jump was so outstanding it went beyond the capabilities of the equipment used to accurately measure the jump. In this activity students explore the progression of the world record for the long jump using a variety of techniques, statistics and graphical representations. Watch the video to help put the activity into context. Does Bob's jump statistically represent an outlier?

This activity introduces Radians as the arc length around a circle of radius one unit and the equivalent angle measurement. Students are then provided with a unit circle on the Cartesian plane to see how the arc length relates to the distance to the x axis (sine). Students are provided with interactive content to help explore this relationship.

The relationship between pitch (frequency) and the key (note) tapped on a piano keyboard are mathematically connected. The relationship is a relatively simple exponential function. In this activity students explore this relationship and use it to determine frequencies as they are played on a keyboard.

It starts with an envelope, progressed to a curve and then a whole world of mathematics opens up. From the humble parabola, the curve is transformed and explored using algebra, parametric equations, rotations, calculus (including implicit differentiation); this activity has got the lot! Hours of enjoyment.

A triangle circumscribes a rectangle. The triangle is not unique, so what is the minimum area of the triangle that circumscribes the triangle? Students use the dynamic representation on TI-Nspire, data capture and more to explore this problem with some elegant solutions.

How do you work out the area of a parallelogram? Students are provided with a dynamic representation of a parallelogram which they use to explore the area. By locking the area, students see that infinitely many parallelograms still exist, however they all have the same base and height. Students are then provided with an animation that helps explain their observations.

World sporting competition tables generally focus on the total number of medals won, is this a fair comparison? What if the comparison was based on medals per head of population? What about a comparison based on GDP (Gross Domestic Product)? The activity includes a wealth of data and options for students to compare perceived success in the sporting arena.

Draw a triangle and measure the area, now lock the area so that it cannot change. What forms might the triangle take now? Students explore the family of triangles created when the area cannot vary. Based on their findings, students work towards the formula for the area of a triangle.

Students use calculus (solid of revolution) in both Cartesian and Parametric form to determine the volume of an ellipse when it is rotated around the axis to form an ellipsoid (football). Students also use arc-length to check measurements.
