HEMS Seminars

The Herbst Family Foundation, created by Lee and Arthur Herbst, provides an endowment to CRR to provide Saturday workshops for elementary, middle, and high school teachers. These Herbst Enrichment Mathematics Seminars (HEMS) are taught by exemplary classroom teachers who present meaningful content and model excellent teaching strategies. Due to the generosity of Lee and Arthur Herbst, teachers from partnership schools/districts receive stipends for their participation.

PLEASE NOTE: Teachers from non-partner schools will incur a fee in order to attend workshops, and they will not receive a stipend for their attendance.

HEMS: Student Engagement in Math and Encouraging Your Students to Carry the Mathematical Conversations!

by Tori Rios 8/17/19 and 9/14/19 


Description: Think about the last good conversation you had; the last bad one.  Think about the last “tweet storm” you encountered and think about the effect that has on not just you, but the culture of learners you interact with each day.  Clear communication has never been more important. And it’s not only true in the world outside our classrooms, but in the math setting as well. Rarely do we think of conversation as a way to learn math.  In this workshop, you will look at academic articles, explore different teaching strategies and learn how to incorporate a variety of activities in your own classroom that foster the idea of learning math through dialogue.  Come ready to be a part of the conversation and be inspired to stretch yourself in how you approach teaching in your classroom. This presentation is intended for all high school math teachers with specific examples of activities from Geometry, Algebra, and Statistics.



Tori Rios has been a part of Flowing Wells High School since she started as a long term substitute in their math department in 2008 after receiving her degree at the University of Arizona in Probability and Statistics.  Realizing her passion for students, she went back to school to obtain her teaching certificate and has been a full-time teacher since, focusing on Algebra 1, Geometry, Algebra 2, and most recently, AP Statistics.  In her time in the classroom she has played an integral role in planning the Geometry curriculum for the CCR standards transition for the district. Realizing the importance of hands-on and interactive experiences for students to learn, she was involved in the MESA program on campus for 5 years.  In addition, she frequently seeks out opportunities to further her instruction, most recently participating in Project Compass at the University of Arizona where local math teachers explored the importance of both grasping math content in all its connective pieces and how dialogue can be obtained in the math classroom, pushing students to a higher level of understanding.
