Essential Understanding

The student uses age-appropriate tools and models to investigate the natural world.

Science Background

Classroom Case Studies Grade K-2: Annenberg Learner (website) - Class case studies enable examination of how children in grades K-2 think about and work with measurement concepts, including those of area and relative size. Also includes strategies for presenting related content in your own classes.
