You will find a 9-month curriculum that can be started any time of the year (not just September). There is a workbook for 2 year olds, 3 year olds and 4 year olds. In each workbook subjects include Reading, Writing, Arithmetic, Science, Social Studies, Arts & Crafts, Music and Physical Education. All 200 plus laminated page courses are included in these spiral bound workbooks. The workbooks are made to be durable and nearly indestructible. Plus, when used with the included special marker the pages can be wiped off with a wet cloth and used again and again.
