101+ Sensory Activities For The Classroom. Ideal for preschool, kindergarten, and primary classes, each activity has been developed to attract and keep children's interest by using a multi-sensory approach, in order to improve children's learning and behavior. Activities are organized by month (the book begins with September activities and ends with August activities), so educators can quickly choose activities that correspond with seasons, holidays, and educational goals throughout the year. Each activity also includes a "Letter to Parents" that may be copied and sent home with the children. These specially tailored letters provide a brief description of the activity, explain the educational purpose behind it, and suggest related home activities to help the children grow.
