Investigations and the CCSS
Learn more about Investigations and the Common Core State Standards at third grade. The sample Session, Same Area, Different Perimeter; Same Perimeter, Different Area, makes explicit ideas about area and perimeter that students have been encountering. It is designed to be incorporated in the fourth Grade 3 unit, Perimeter, Angles, and Area: 2-D Geometry and Measurement. The instructional plans layout Session-by-Session changes to each Investigation in that unit.
