This NEWLY UPDATED bundle is aligned with a first grade Properties of Matter science unit (SC.1.P.8.1). The worksheets and sorting mats allow for students to sort objects by observable properties, such as size, shape, color, temperature (hot or cold), weight (heavy or light), texture, and whether objects sink or float. This resource is easily organized by each property.What's Included?Table of contents with linkssort by shape: 7 pagessort by color: 5 pagessort by weight: 10 pagessort by size: 5
