About the store

I'm a middle school math teacher who has 20+ years experience teaching from 1st grade to Algebra I. I currently teach math seminar and gifted and talented classes. I believe in the importance of strong, research-backed intervention strategies for our struggling learners. I also know the value of differentiation for our accelerated students. I create math activities that support student growth at every level, using proven instructional principles to build conceptual understanding and procedural proficiency.
