The Montessori approach to learning is extremely popular and its method of teaching through interactive play, in particular, has been used by White Star to create My First Book of Shapes; a fun, stimulating, book for children aged 2-4. It has been designed according to Montessori educational and academic principles and has been created especially to enhance the cognitive development of the reader. Developed using progressive complexity, My First Book of Shapes encourages children to learn to identify different shapes, and then put into practice what they have learnt by connecting similar shapes and grouping related shapes together. Finally the book helps them build on stages one and two to combine what they have learnt with things they might already know, allowing for independent play and a fun learning experience.
