## Fair Games

- Units of Work
- Statistics
- Level Five

Many games of chance and activities in maths text books involve rolling two dice and combining the scores, usually by addition. Students often find the probabilities of such events difficult to calculate as they are confused between events (for example a score of 4) and outcomes (for example 3 and 1, 2 and 2, 1 and 3). This unit makes use of a variety of activities where the number of outcomes in the sample space is clearly different from the number of events.

## Statements about Probability

- Units of Work
- Statistics
- Level Two

In this unit students make spinners to show the probability of events. They will make statements about probabilities shown on spinners and evaluate statements made by other classmates.

## Way to Go

- Figure It Out Activities
- Statistics
- Level Two

This is a level 2 statistics activity from the Figure It Out series.

## Sneaky Snakes

- Figure It Out Activities
- Statistics
- Level Three

This is a level 3 statistics activity from the Figure It Out series.

## Houses

- Units of Work
- Geometry and Measurement
- Level Three

This unit seeks to connect learning outcomes across all five content strands, number, geometry, statistics, algebra, and measurement. The context of houses is used to develop concepts such as drawing and modelling 3-dimensional objects, using co-ordinate systems to locate position, finding all the possibilities of events, and identifying paths through simple networks. The unit provides an excellent vehicle for students to use a broad range of problem solving strategies.
