This is a mathematics module that has been donated with a battery-operated interactive teaching machine. There are five books, each containing a 6.75” vinyl record and a spiral-bound activity book. Books 1, 2, and 4 include a printed pad with tear-off worksheets. A “Teachers’ Notes” book and an “Administrative Guide” book are included in the kit. There are five cardboard pull-drawers containing colored paper markers for use with the workbooks. The student can randomly access the lesson via a control on the left side of the machine. The student loads the record, places the exercise book on the work surface and begins the lesson. Donor is listed as Production Manager on the credits page of the module books.
