compare the parallel cross-sections of objects and recognise their relationships to right prisms

How Bloomi helps with this

This is a readiness-year topic that builds towards the next NAPLAN year. Bloomi practises it as curriculum mastery, never test drilling.

What this looks like in the classroom

• using objects made of foam or polystyrene, slice along different cross-sections, and record the different shapes of faces that result; comparing cross-sections of different objects
• using different pieces of fruit, slicing across different cross-sections, drawing the cross-section; reporting back to the class the results of the investigation
• observing and drawing the shapes resulting from different ways of slicing through familiar objects; for example, slicing carrots at different angles or cutting through playdough models of objects; using playdough models, fruit or similar to establish which objects can be cut in such a way that the cross-section will always be the same shape
