This board book, along with its companion, Letter Work, brings popular Montessori pedagogy into book format for the first time. Montessori students learn to conceptualise relative quantity before learning the numerals. Numbers are taught first as quantities (instead of names), with number rods that can be manipulated and rearranged. Numeral tiles encourage children to trace each number with their finger. This book honours that tradition by emulating the standard classroom materials with a cumulative red and blue number rod, as well as touchable, traceable numbers and Montessori directed language to encourage understanding. The numbers from 1 10 are introduced first as quantities to count and then as numerals, providing young children with an alternative way, a Montessori way, to learn their numbers.
