Curriculum content descriptions

connect objects to their nets and build objects from their nets using spatial and geometric reasoning (AC9M5SP01)

Elaborations
  • designing and constructing exact nets for packaging particular shaped items or collections of interest, taking into consideration how the faces will be joined and how the package will be opened
  • visualising folding some possible nets for a range of prisms and pyramids, predicating which will work and which cannot work, and justifying their choices, based on the number, size and position of particular shapes in each diagram
  • sketching nets for a range of prisms and pyramids considering the number, shape and placement of the faces, and test by cutting and folding
  • investigating objects designed and developed by First Nations Australians, such as those used in fish traps and instructive toys, identifying the shape and relative position of each face to determine the net of the object
General capabilities
  • Critical and creative thinking Critical and Creative Thinking
  • Numeracy Numeracy

reSolve: Bifold Boxes

This lesson challenges students to use proportional reasoning to explain how changing the size of a square will affect the size of a box folded from that square. Students fold an origami box from a square of paper and record the dimensions of the resulting box. They then fold a box from a square of paper four times the ...

Throw a Shape - Calculate

In this game, students throw dice to determine the number of edges and vertices of a 3D shape, they then use physical materials to build their shapes. The game gives them an opportunity to practise geometric reasoning, identifying shapes based on their properties and visualising objects in three dimensions.
