# The Equipartitioning Learning Trajectory: a K-5 Foundation for Rational Number Reasoning

### A Massive Open Online Course for Educators (MOOC-Ed)

The Mathematics Learning Trajectories MOOC-Ed series presents Learning Trajectories (LT) as a framework for interpreting and implementing the Common Core State Standards for Mathematics (CCSS-M). Our first course introduces the Equipartitioning LT. Grounded in fair sharing activities that create equal-sized groups (from collections) or parts (from single wholes), Equipartitioning provides a robust foundation for studentsâ€™ conceptual understanding of division, multiplication, fraction, and ratio. We recommend this course for elementary and middle grades educators seeking a deeper understanding of studentsâ€™ learning of fundamental mathematics for their own instructional practice.

The MLT MOOC-Ed series is brought to you by the GISMO Research Group at the Friday Institute for Educational Innovation at NC State University, led by Dr. Jere Confrey and Dr. Alan Maloney. The MLT team will provide instructions, suggest resources, contribute to discussions, and answer questions from course participants in each lesson in the course.
