A. M. Joosten writes from his deep and long classroom experience of the many activities to use with the movable alphabet for solidifying language skills. He is always sensitive to situations where a child may have come late to the House of Children and therefore might need incentives to engage with the materials. This valuable information is for the directress whose children need extra help in learning the sounds of the sandpaper letters. In the "how-to" details, Joosten is careful not to correct the child but to structure a lesson so that practice and repetition entice the child. Some suggested activities involve small group work and many involve movement. The children will not even realize how many different activities are directed to increasing their fluency with the sandpaper letters and the movable alphabet.
