Filling in geometric shapes with a continuous colored pencil line prepares students in the Montessori Primary Casa, or classroom for three to six year olds, for cursive handwriting. My Montessori Coloring Book of Shapes helps children refine and perfect their fine motor control while simultaneously reinforcing what is practiced in the Casa. Written and illustrated by AMI Primary Diploma holder Mary Da Prato, My Montessori Coloring Book of Shapes defines Montessori prerequisites for successful handwriting that can be implemented at home.
