Heather Trefz

I am the Junior High Math and Science Teacher, High School Pre-Algebra Teacher and the k-12 504 Coordinator. 

The expectations in my classroom are easy:

1. BE Prompt: if you come in after the bell you will be counted tardy

2. BE Prepared: bring everything you need - if you don't have something for study hall, I will find you something

3. BE a Participant: be a part of the class discussion and participate in the activities for full credit.

4. BE Polite: use your manners and be respectful of others in the classroom.
