Implementing Mathematical Modeling in the Elementary Grades and Beyond

9:30 AM – 11:30 AM
Room: Assembly E – Fifth Level

Mathematical modeling is an important topic of study and mathematical practice in the newly adopted Common Core State Standards in grades K-12. This symposium will engage the SIAM audience in considering ways in which early introduction to mathematical modeling can promote computational thinking. Brief presentations from a team of mathematicians, math educators, teachers and undergraduate STEM scholars will demonstrate how they collaborated on Mathematical Modeling tasks in the early grades. They will share case studies of how MM enhanced the teaching and learning of mathematics by bringing in the real world context to students and enriched the learning environment.

Organizer: Jennifer M. Suh
George Mason University, USA
Padmanabhan Seshaiyer

Family of Problems


Family of Problems is dedicated to building a warehouse of creative, interactive, flexible problems for innovative math teachers. All the problems within this site have been successfully used by experienced math teachers in the classroom. Problems are grouped in threes based upon related content and learning concepts. Each problem is documented with a front door, lesson plan, and black line master; and links to its two closely related problems. The problems are listed below organized by grade level, big idea, and alphabetic order. Enjoy!
