     Sand Ridge - Sodaville Classes

Principal - Cara Osborne


Mrs. Osborne

Sand Ridge Charter School began as a "private alternative school" 23 years ago. It first became a public charter school in 2002. The educational motif is an emphasis of "back-to-basics" through a solid curriculum of Core-Knowledge, Riggs Institute, and Saxon Mathematics.

Currently, with an enrollment of 345 students K-8th our two salient underpinnings for excellence are a personalized education through maintenance of small classroom sizes and engaged parental involvement. These foundational pillars have provided a hallway for our students to consistently walk through in their exemplary academic achievements!

I grew up in Indiana, graduated from Portage High School in 1990, attended Ball State University in Muncie Indiana and graduated from there in 1995. I hold a dual degree in elementary education and special education. This is my eighth year teaching.

I really enjoy teaching 3rd grade because 8 years olds are very eager to learn and they find wonder and excitement in all things. Whether we are visiting distant planets in our solar system or looking into the past at Anthony and Cleopatra we always find fun and creative ways to learn about the world in which we live.
