Literacy in the Early years Foundation Stage is broken down into two aspects
Writing is an essential skill children will learn, which begins with mark making. Encouraging young children to mark make will develop their hand-eye co-ordination and fine motor skills as well as enabling them to practice putting pencil to paper.
Introducing children to books at an early age allows children to become familiar with books, enjoying the pictures and the stories and sounds read aloud by an adult. Even if a child is not at the age of beginning to read, they will benefit from hearing the words read to them and start to become familiar with different sounds, eventually beginning to recognise letters and words.
In Nursery the children take part in squiggle whilst you wiggle sessions. First they paint each other to help them get familiar with the parts of the body. Then they will learn a new gross motor movement to a piece of music. They will dance using this movement and use it to make marks, this can be in foam, on paper, in sand etc.
They will then use this action to think of letters they can form that use this shape.
These sessions are great fun but most importantly help your child to be confident mark makers.
