Activity
Students may need experience with simpler forms of this problem before attempting this page. Similar tasks can be modelled simply with objects on a desktop. For example, these objects are placed on a desk:
Students can sketch the views from desk level of the front, right, left, and back by crouching down until their eyes are at desk height.
Then reverse this exercise by giving students two views of objects that have been placed on a desk in a different position and asking them to recreate the view looking down. For example:
Transferred to the problem of Mārama Island, the method for finding the top view might be:
1.
Discussion will vary. As a starting point, you need to work out where north is in relation to the view in each picture. Mount Mārama is in the west, the radio transmitter is in the north, and the lighthouse is in the south-east.
