This unit focuses on the social studies aspects of environments/ecosystems, as laid out in the 3rd grade Utah Core Curriculum. There are 6 lessons, plus a unit closure in this unit.
This document set also includes additional ideas/resources to use in this unit. The additional resources you receive are: curriculum diamond, layered curriculum activities, student activity instructions (for both small group and individual work) with rubrics, graphic organizer for research, and teacher's grading rubric.
I have used this unit in my classroom and my students absolutely loved it. They always say it's their favorite unit during the year.
