Overview

This 6-day unit is designed for 5th grade students to master converting customary units of length, capacity, and weight—excluding miles and tons—in alignment with South Carolina State Standard 5.MGSR.2.1, and Minneapolis Public Schools Standards MPS.SP.1 and MPS.C.1. Instruction will integrate math practices and problem-solving strategies promoting collaboration, reasoning, and real-world application. The lessons include pairing, small group work, interventions, and closure activities tailored for diverse learners.
