Use this highly engaging teaching presentation when focusing on the features of 3D objects. Students follow the story of Professor Dede and his new invention called ‘The Dimensionator’. They help the professor test the machine by using their knowledge of 3D objects and along the way, uncover a mystery involving a lost vault of inventions.

The presentation displays the 3D objects using the 3D model feature in PowerPoint. This allows the models to be animated and viewed from multiple angles. There are four different chapters that all have a particular focus.

1. The Peculiar Plans

The professor has found the plans for a fascinating new invention. He needs help calibrating the machine and requires the students to provide examples of real-world objects. The students hold up their objects for Professor Dede to scan into the machine and calibrate it correctly.

This chapter includes a task that uses our 2D Shapes and 3D Objects Worksheets.

2. The Prism Predicament

Students use their knowledge of the features of prisms to operate the machine correctly and create multiple 3D objects. The PowerPoint uses engaging animations to visualise the transformation process.

The remaining chapters all use the Draw a Town with 2D Shapes resource to uncover the mystery left behind by professor’s grandmother.

3. The Problematic Pyramids

The machine’s second setting involves pyramids. Students input the correct number of faces, vertices and edges to create different pyramids.

4. Polyhedrons and Pals

The final chapter looks into objects that have curved surfaces and an advanced polyhedron. Students will create a sphere, cylinder, cone and dodecahedron. The terms used to describe these objects can differ. Alter the text in the presentation to match the terminology used by your school where necessary.
