About the store
I taught all levels in elementary education for 35 years and instructional technology for 6 years. I started out teaching in Florida, moved to Washington State, and taught in the same district in California for my last 36 years. After retiring ten years ago, I did some consulting and taught educational technology classes for the Orange County Department of Education. I volunteer at my local elementary school and continue to make educational materials for friends in my old district and help them with writing grants.

Teaching style
I always believed in a student-centered classroom with lots of cooperative learning. I started using computers in the classroom about 1977 and never looked back. Technology became one of my strongest teaching tools.
