When children write a random string of letters, they are likely in the _____ stage of writing development.

When children write a random string of letters, they are likely in the scribbling or preliterate stage of writing development. This stage typically occurs between the ages of 2 and 4 years, where children begin to experiment with writing instruments and mark-making. During this stage, their writings consist of random letters and shapes, as they have not yet developed an understanding of the connection between sounds and letters or the structure of written language. This phase is crucial as it lays the foundation for later stages of writing development, where children will start to form recognizable letters and words. It reflects their exploration and experimentation with written language, showing the initial steps towards literacy.
