"As with all things Montessori, students begin with the concrete and move to the abstract. Montessori: Planet Work introduces readers to the sun at the center of our solar system before moving outward to the eight planets. Each planet is textured for greater interactivity, and a final gatefold spread gives added spatial context. Young children will absorb the age-appropriate information and gain a better sense of their place in the universe"--Provided by publisher.
