Principal's Welcome

Welcome to Mars Area Centennial School!

The Mars Area Centennial School Staff and I are thrilled to welcome you to the 2019-2020 school year! We hope that you had a wonderful summer full of positive experiences and lasting memories. Being prepared and excited to enter the Centennial School is a very important component to a successful start and for the sustainability of a successful school year! The Centennial Staff and I are looking forward to continuing to provide a positive educational experience that builds on our students’ prior academic knowledge. While building on that prior knowledge, we will strive to educate, promote retention, and emphasize the value of the educational and personal learning experiences you will encounter this year.

The Centennial School will continue to operate as an elementary school with a unique setting. This educational setting will allow for transition and will eliminate the self-contained classroom setting. Students will transition between two, possibly three, classrooms during specific core subjects. This will put more responsibility on the students to stay organized and to adapt to transitions throughout the day.

This year the Centennial School will be home to ten 5th grade classrooms and eleven 6th grade classrooms. Students in 5th and 6th grade will be working with a team of two teachers throughout the day. One teacher will be responsible for instructing the English Language Arts and Social Studies curriculum and their partner teacher will be responsible for teaching the Math and Science curriculum. Some students at the 6th grade level will be working with a team of three teachers. These teachers will provide the same educational experience as our teams of two. Each teacher within the team of three will be responsible for teaching a core subject: English Language Arts, Math, or Science and Social Studies. With academic expectations set high for our students, the goal of the Centennial School will continue to:

  • challenge our students through differentiated instruction so that all students’ learning needs are met.
  • guide them to be independent thinkers and problem solvers.
  • help them grow socially and emotionally for continued success!
  • provide them with opportunities to be M.A.R.S. students through our school wide expectations.

With our students’ opportunity to experience more than one core subject teacher throughout the day, a great deal of time and effort was placed on classroom placement. Careful consideration was given to the input provided by our families and staff regarding your student’s learning style. Thank you in advance for being positive with your child regarding their selected teacher. I can assure you that all of our staff members are highly qualified educators and will work very hard to provide a positive learning atmosphere for your student(s).

The Centennial School also promotes an active parent partnership. A quality learning experience is built on a cooperative effort among parents, students, and staff. We encourage parents to be a part of the learning experience here through parent communication. Please know that we are here to help ensure that our 5th and 6th grade students’ experiences are memorable.

Again, the Mars Area Centennial Staff and I welcome you and look forward to achieving the high academic goals we have set for the 2019-2020 school year!
