Hello from the math team! This website is designed to keep you updated on what's happening with mathematics at school. There are also resource pages for families and caregivers. We hope they are helpful. Let us know!

Polly Wagner:

We are here to support you, your child, teachers, and community members.

Mrs Graichen:

Please reach out to any of us at any time if you have questions about the teaching and learning of mathematics.

Mrs Desorgher:

Kent Haines is an instructor at the University of Alabama. He used to be a middle school teacher, has written math curriculum and has a math game website and blog.

We are in a unique time in our history as a school, state, country and world. During the pandemic our primary concern is the welfare of our students and community -- staying safe and well is our highest priority.

As of April 3rd the school has been providing remote learning opportunities for our students. Each classroom teacher has offered weekly learning plans for students and families on the Erving website. The goal is to support our students with engaging and interesting activities to do at home. We know this can be particularly difficult on families who are balancing home and work life ... and now are asked to provide school-like experiences at home for their children. We know it's a lot!

If you have any questions about the mathematics your child is doing, please don't hesitate to reach out to your classroom teacher and/or someone on our math team: Polly Wagner:, Elizabeth Desorgher:, and Allison Graichen:
