Principal's Welcome

On behalf of Mars Area Centennial Staff, I am excited to welcome our students and their families to the 2021-2022 school year! Over the past summer months, I hope you were able to stay healthy while finding ways to relax, rejuvenate and recharge. As we move into a new academic year, academic expectations and learning goals are always set high for our students! Those expectations and learning goals for our Centennial students will continue to be:

  • to meet all of our student’s learning needs through differentiated instruction.
  • to challenge our students to meet academic expectations and annual goals.
  • to guide them to be independent thinkers and problem solvers.
  • to provide them with opportunities in developing and meeting their socially and emotionally needs for continued success!

As in years past, 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 previously experienced at the Elementary School. Students will transition between two classrooms during specific core instruction, as well as their daily special areas class, W.I.N. (What I Need) Time, lunch and recess. These transitions will put more responsibility on our students to stay organized and to adapt to numerous classroom transitions throughout the day.

This year the Centennial School will continue with ten 5th grade classrooms and ten 6th grade classrooms for daily instruction. At the 5th grade level, a teacher will be responsible for instructing the English Language Arts curriculum and their “partner” teacher will be responsible for teaching the Math, Science and Social Studies curriculum. At the 6th grade level, a 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.

As we look to reopening our schools to our students, we are very aware and understand that the past academic year presented many challenges. Through a global pandemic, we learned how to navigate through new challenges while striving to provide a quality education for all of our students. With your partnership, we were able to keep our schools opened and our students successful in the classroom. We ask for your continued partnership and support, now more than ever, to ensure that student safety and academic success continues during the 2021-2022 school year. We will continue to recognize that in order to be successful in school, our students need support in and out of the classroom from all stakeholders involved. We recognize a strong partnership with our families is vital for flexibility as the global pandemic continues to present challenges that change on a daily basis. Please remember, that our partnership and shared responsibility for our children’s safety and success is extremely important to us and will remain a top priority.

Again, it is my pleasure to welcome you to the 2021-2022 school year! I look forward to leading our students and staff in a direction to meet all of our academic goals for the 2021-2022 school year!
