Imagination doesn't come down from above fully developed, and plant itself into a mature mind like a man moving into an empty house. Like any other function of the mind, it starts as the merest seed of a power. It grows according to what nourishment it gets. Childhood, the age of wonder and faith, is its window of opportunity to grow. Children should know the delight of living in faraway lands, of being someone else living in a different time, a wonderful double life.

How can we introduce our children to faraway lands and people from different times, to those ideas that can encourage the habit of imagining? One way to do this is through art. Art can help your history lessons come to life, and give children a starting place for their own imaginations.
For example, if you and your children are studying ancient Japan, you can encourage your children's imagination by first of all sharing descriptions of what it would have been like to live in and experience that time and culture. Then you could share artwork depicting what that time was like. Ask them to describe to you what they see. What is happening? What would they do if they were in the painting? Encourage them to put themselves in the painting-- in the time and place you are studying.
