Students explore the features and properties of three-dimensional (3D) objects to identify and create nets of 3D objects.
This lesson uses unit cubes and hollow objects to demonstrate the concept of volume and the units used.
Use this task to reveal if the student can see in their ‘mind’s eye’ the transformation from a 2D net to a 3D object.
This is a five-page HTML resource about solving problems with nets of three-dimensional solids. It contains one video and three questions, two of which are interactive. The resource discusses and explains solving problems with nets of three-dimensional solids to reinforce students' understanding.
Zoom inside a glass prism and see why glass makes light bend, and how the glass molecules make different colours of light bend different amounts.
Watch this video to learn about the features of 2D shapes. How is it different from the features of 3D shapes (solids)? Some examples of solids that incorporate 2D shapes are mentioned in this video by Sanchit - for example, a cube has six square faces. What other 3D shapes could you make that has at least one square face?
