Cassowary fractions
Students are presented with a scenario in the form of an incident report such as ëfour cassowaries sick with a virusí. Students select a geometric shape to form their pens, then choose a radial or rectangular tool to divide the shape into appropriate sections. The idea of equivalent fractions is introduced at the end of the incidents. Different incident reports require different fractions, with the most complex being twelfths. In some cases only one of the tools is available and sometimes not all of the shapes are available.

Cassowary ecology quiz
This provides a set of information about the cassowary, such as its height compared to other birds and the number of eggs it commonly lays compared to other birds. Students complete quizzes about the facts presented, with the answers to each question being a common fraction. One screen provides the student with strategies that could be employed to improve the sustainability of the cassowary. Students can select strategies they think should be employed and see the effect on the cassowary.
