Almost every interaction you have with your child is preparing them to become a reader and writer. Your child has been learning to write since before they could hold a pencil or crayon. Remember when, as babies, they first discovered their toes, trailed their fingers through their food or scratched marks in the ground with a stick? These are all early writing skills. Before your child can become a confident, legible and fluent writer they need to have lots of experience in developing large & fine movements, recognise patterns. Pegs are a great resource to develop the muscles needed for writing for all ages groups from sorting, pegging around baskets to hanging out the washing.
