Welcome to Tres Rios Elementary School

Welcome to Tres Rios Elementary School, home of the Pumas! We are a K- 8 school in the Littleton Elementary School District #65. Located in Tolleson, Arizona, approximately 18 miles west of downtown Phoenix, we enjoy a friendly, family-oriented, small town atmosphere.

At Tres Rios we believe in the development of learning communities, and that every child can and will learn if provided an appropriate environment. We are committed to providing the tools to help our students be healthy, successful, lifelong learners. We offer a variety of programs to meet the needs and interests of our students, including an athletic program, special education, a band program and gifted program, as well as state-of-the-art technology.

We recognize the value and importance of parent/guardian participation in a child’s education and welcome your involvement. We have provided several ways to help you stay connected, including a Facebook page, Twitter, and this website. We thank you for your interest in our school and for supporting your child(ren), as we work together to educate and prepare our most precious assets, our children, to take on the world!

A Message from our Principal

Tres Rios Families,

How can it be we are already in the month of February? Thank you to all who joined us for our Family Math Night. It was fun to see all of you getting “mathy” with your children.

What a fabulous turnout for our Focus Schools = More Choices Night! We are excited that you continue to choose Tres Rios, and we are looking forward to becoming a service learning school next year. We will be partnering with local community organizations to make Tres Rios and our community even better.

Please make sure to have your child’s registration card turned in by February 12 so that you can make sure your child is registered for the 2016-2017 school year.

Have a fantastic February!

Karen Grose
