# Viewfinder: all angles [ESL]

TLF ID L9992

Explore visual perspectives of solids such as cylinders, cones and cuboids. Match a 2D photo of a group of 3D objects taken from a different viewpoint. Identify the relative positions of the solids by comparing 2D outlines and colours. Rearrange the objects on a base grid until the view matches the original photo. One of three levels is generated randomly; each focusing on a different aspect of spatial perception. This learning object is one in a series of four objects.

#### Educational details

Key learning objectives
• Students interpret and visualise 2D representations of 3D objects.
• Students place objects to make 3D models from plans and projections.
• Students translate between 2D representations and 3D objects.
Educational value
• Illustrates that the perceived shape of objects depends on the observer’s viewing point.
• Displays a group of objects from different perspectives.
• Provides visual cues about the shape of objects to construct a three-dimensional scene.
• Enables the student to select from four levels of difficulty.
• Features modified language for English as a Second Language users.
• Includes a glossary of terms used in the activity.
