Play is a significant medium for children's literacy development. As children engage in play activities, they are given opportunities and the motivation to show what they already know about reading and writing systems. Previous literature has shown that a literacy-rich environment increases the number of literacy activities available through play. The effect of materials appears to be enhanced by adult use of appropriate forms of scaffolding to encourage children to integrate literacy props into their play. Moreover, play intervention can facilitate children's literacy development and reveal different ways adults can interact with young children during such activities.
