The first and second grades are busy, active classrooms full of children reading, writing, learning math, discussing their learning, and expressing their faith. Students develop many skills, such as visualizing, comparing and contrasting, making connections, and determining the main idea to help them understand the material they are reading.

The Great Minds Math program is used to teach children to use higher level thinking skills, learn the basic facts, and continue to deepen that knowledge.
In Religion class students learn the basics of the Catholic Faith, such as learning the parts of the Church building, the parts of the Mass, the life of Jesus and the Holy Family, and memorizing basic prayers. Students also prepare for sacraments and study the weekly scripture readings. Students in these grades also go to one hour of Catechesis of the Good Shepherd each week.

Science, social studies, handwriting, and art are also taught as part of the weekly classroom schedule. Students attend music, physical education, and engineering classes two or three times a week. There are two music concerts each year.

Students in grades 3-4 are offered a rigorous, experiential curriculum.
