Please see individual unit listings for complete previews, details, and ratings of each stand alone unit. By popular demand Core Rigor has compiled all of the Grade 5 NGSS standards into a mega bundle of all Earth Science, Life Science, and Physical Science NGSS Units. The research and design of this bundle evolved over the course of a years time, with some activities having suggested science notebook activities and others having printable activities that can be glued into notebooks when completed. In either case, representations of presenting arguments, initiating engineering design, and higher thinking with collaboration are infused throughout the units. The goal of these units were to save busy teachers time and provide efficiency in presenting effective "hands on" science instruction in a practical yet fulfilling way. Individual NGSS units for grades 3 and 4 are now in the works and Complete curricula for these grades will be available by August 2016.
