All curricula developed for Holy Trinity School in the Archdiocese of Philadelphia are, first and foremost, based on the teachings of the Catholic Church.  In addition, our curricula reflect the Pennsylvania Learning Standards, the Archdiocesan Guidelines, and the standards of professional education associations.  

Along with English Language Arts, Mathematics, and Religion, Social Studies and Science are added as core subjects in this educational unit and become graded subjects. 

In ELA, both the Fountas and Pinnell reading program and thematic literature units are implemented.   

Students move from basic math facts and skills toward more complex algebraic and gemoetric concepts during their time in the Intermediate Unit.

Throughout this educaitonal unit, students grow in the knowledge of their Faith using the workbook series The Spirit of Truth and The Catholic Children’s Bible.  A variety of engaging and interdisciplinary activities including geography, history, and art are incorporated into the Intermediate Unit Religion curriculum.

For Social Studies, The Alexandria Plan is used - a Common Core history program that is literature-based, using historical and informational texts.  The Alexandria Plan encompasses both World History and US History in a three-year cycle.  Though the topics are the same, instructional techniques, strategies, and resources vary at each grade level.  Students will grow in knowledge of geography by reading and analyzing maps, learn about US history beginning with the 13 original colonies through the end of the American Revolution, and gain an understanding of civics and government.  

Science in Grades 3-5 is S.T.E.A.M.-based and includes a variety of topics in Physical, Earth, and Life Science.  All three grades are involved in the annual Invention Convention held during the second trimester.
