Students explore three different ways to generate a sequence on their calculator: recursively, using the sequence command (lists) and finally using the function editor. The memory locations a and d work nicely with the formula for an arithmetic sequence and make for a more dynamic and user-friendly environment.
This activity includes a video tutorial.

Students review probability as a measure of likely chance to occur, perform simulations of experiments using technology including the identification of factors that could complicate the simulation of real events, create and use a sample space to determine theoretical probabilities and expected values, all through the context of the popular board game Monopoly™.

Two popular word games in one activity. Students use a program to extract letter frequencies from text and uses the data to analyse two of the most popular word games: Scrabble and Wordle. Students develop strategies for the second game and test them using the program: TIgram.

Watch Paul discusses the kick, we discuss the calculus and more.
There is no doubt, a kick directly in front of goals is more likely to be successful, but where is the best place if you are near the boundary line? This activity starts with shooting for goals in soccer before heading out to the MCG and a magnificent kick from the boundary by AFL great, Paul Salmon. Did he find the best spot from where to launch his kick?

This activity is part of the coordinate geometry series. In this activity students use the midpoint tool to explore and establish the formula for the midpoint of two points. Students then go on to explore the path of the midpoint for a fixed point and a point on a line.

Watch Activity Tutorial
In this activity students watch the above video to gain an understanding or parallel and perpendicular lines in the context of coordinate geometry. After watching the video students answer a series of questions followed by a small investigation into quadrilaterals with vertices on the midpoints of a larger quadrilateral.

This activity combines the result of the Circumcentre, Orthocentre and Centroid activities to locate the Euler line. The problem is explored entirely on the Cartesian plane and provides ample opportunity for students to demonstrate an understanding of perpendicular lines and midpoints, determination of equations and solutions to simultaneous equations with a purpose.

This activity is aligned with the Circumcentre and Orthocentre activities forming a natural progression for the Euler line activity. Students calculate gradients, equations to lines, solve equations simultaneously and use the calculator's tools to check their answers.

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!
