### You Reckon?

In this activity students are introduced the idea of Plausible Estimation (PE). PE underpins major decisions made in private and public lives. PE tasks allow students to appreciate how powerful simple mathematics can be when making decisions about important topics by solving problems faced by aid agencies,...

### Speed Cameras

In this activity, students are presented with the question: “Do speed cameras reduce road casualties – or not?”. The activity is set in the context of media reporting to explore ideas of randomness, probability and drawing conclusions from data. A secondary theme is the mathematical modelling of a real situation....

### Sending Texts

This Nuffield investigation involves determining the number of text messages sent if four people send texts to each other, and then extending this for different numbers of people.

*Key processes applicable to this activity are:

*Representing - choosing method of representation to show the texts sent...

### Save a Baby Kangaroo

In this activity students take on the role of an adult in the Australian Outback who whilst out horse riding finds a female kangaroo that has just been killed on the road by a passing truck. Her joey is still alive in her pouch. Through video clips, photographs and data, students become familiar with a range of...

### Paper Sizes

In this Nuffield investigation students study paper sizes in the A and B international series, exploring relationships within each series and between the series.

The key processes are:

*Representing - identifying the mathematics involved in the task and developing appropriate representations.

*...

### My Music

This activity provides the opportunity for students to analyse the similarities and differences between genres of popular music with particular focus on the variable measures of tempo. Students work in small groups and listen to different music tracks, measure the tempos and interpret and present the results....

### More Miles for Your Money

Based on information and guides provided by the Department of Transport, this Cre8ate maths activity introduces the cost benefits of improving the aerodynamics of the cab section of a truck. Mathematical connections involve using calculators and spreadsheets to work on conversions and percentages in the context of...

### Keeping the Pizza Hot

This activity requires students to consider the problem of maximising the market available to a pizza shop through the ability to keep a home-delivered pizza warm for longer. Students use a mathematical model to explore the issue that a pizza home delivery business faces in ensuring that the pizza arrives hot! They...

### Hide the Spies

This Nuffield activity is set in the context of a park. Students determine where spies should sit in the park that has a square grid of benches, interspersed by bushes, so that they cannot see each other. Students also investigate how many different arrangements of spies are possible.

The key processes...

### Helicopter Seeds

This Cre8ate maths flight testing activity requires students to work in groups and, having made their own helicopter seed model from a template, record the landing positions and distances from a central point when the model is dropped from a standard height of one metre. The experiment is repeated ten times and...
