While telling time is not an official subject in the Primary Montessori curriculum, it is an essential lifelong skill that is woven into daily activities in the Casa, or classroom for three to six year old children. An at-home supplement to exercises in the Casa, My First Montessori Book of Telling Time provides isolated images of clocks and their corresponding written times as well as strategies for parents to promote learning readiness in their children. Written and illustrated by AMI Primary Diploma holder Mary Da Prato, My First Montessori Book of Telling Time features calibrated drawings that accurately reflect the positions of the hour and minute hands of a clock every minute from twelve o'clock through one o'clock, and every fifteen minutes from one-fifteen through eleven forty-five. Longhand and digital transcriptions of time accompany each illustration.
