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.
