Have the child look at a house and give you all the detail that he can
see. Call the child's attention to the things missed so that he sees
the reason for making an additional effort. The same exercise can be
followed with any object, a tree, an automobile, or an animal. When in
the house use a picture on the wall, a table, a book case or a coin.
You will find that the longer the child looks at the object the more
detail he will see. The aim is to get him to notice and mention the
details as quickly as possible. After some practice he will be able
to mention them as rapidly as he can speak. This can be made into a
competitive game when there are several children. Keep score of the
number of the details each can write on a slip of paper in a given
length of time.
