Foundation Mastery — Grades 5–8

The gaps that form
in middle school
show up on the SAT.

Foundation Mastery identifies the exact reading and algebra skills that are missing right now — before they compound into high school problems that are much harder to fix.

Designed for grades 5–8. No credit card required.

Why this matters

Most learning gaps don’t start in high school.

The gap

Algebra gaps in grade 6 become calculus problems in grade 11

A fraction operation gap in 6th grade blocks algebraic manipulation in 8th, which blocks quadratics in 10th, which prevents calculus in 11th. The gap compounds at every step. Foundation Mastery finds it at the source.

The fix

Closing one foundational gap unlocks multiple downstream skills

Mathematics has a prerequisite structure. Closing a gap at the root closes gaps in everything that depends on it. Fix the foundation first. The rest follows.
