Singing and watching the pictures in Rebus Songs the child practises many things.
Reading direction: We read from left to right, something which is not self- evident for a child. The clear illustrations make the child ”read” the pictures in the right direction.
Word image: Children can recognize words, their names for example, long before they can read. In Rebus Songs a special word is seen under an explaining picture and so the child gets to know the whole word - like a picture.
