Mathematics

Our mathematics teachers bring decades of combined experience teaching everything from elementary foundations to advanced calculus. We offer multiple curriculum options including Saxon, Glencoe, and Jacob’s—allowing us to match your child with the teaching approach that works best for their learning style.

Not sure which level is right for your student? Many of our high school math teachers provide placement testing to ensure students start at the appropriate level for success. While placement tests aren’t the only factor in deciding where to place students, they provide valuable information and a starting point for discussion.

Need extra support? We offer Math Lab—on-demand tutoring for registered THEO students through Algebra 2, available Tuesday and Thursday mornings.
