Early Childhood

St. Leo’s Early Childhood Program provides a safe, warm and nurturing environment. Through gentle guidance and understanding, the transition from home to school becomes a positive and happy experience. Our curriculum is designed for our children to explore concepts and ideas in a rich environment that is joyful and successful.


Our Early Childhood STEM Program is designed to introduce our children to applied science and technology, as well as to the design engineering process. This is done through hands-on activities that integrate the four STEM components:

  • Science
  • Technology
  • Engineering
  • Mathematics

Everyday Mathematics

Everyday Mathematics is a comprehensive mathematics program that we use in our Early Childhood Program. The hands-on math activities are designed to help children explore a range of mathematical topics and become independent math thinkers.

Elementary and Upper Elementary

St. Leo’s School meets and exceeds the guidelines set forth by the Archdiocese of Newark in accordance with the NJCCCS. Our curriculum ensures high level academics for all our students.

ELA – All our students are expected to read and write effectively and fluently. We use a Balanced Literacy approach to inform classroom practice. Grammar and language mechanics, as well as independent/guided reading and writing are important components of our program.

Mathematics – Our curriculum is carefully designed to build and expand a student’s mathematical proficiency and understanding with a goal to building powerful mathematical thinkers. In our upper elementary program, students are taught the fundamentals of algebra and geometry. We use Connected Mathematics which provides comprehensive coverage of important math concepts, skills, procedures, and thinking and reasoning.

Science/STEM – Our STEM Program is a researched based rigorous and pedagogically sound science/STEM curriculum. We use the Engineering is Elementary Program, as well as the Carolina Science STEM Program. Our Upper Elementary students work together on research based, design engineering processes to find solutions to problems.
