THSF Math vs Singapore Math Dimensions

Which Homeschool Math Curriculum Is Right for You?

An honest, side-by-side look at both curricula — real costs, real pros and cons, and a clear “choose this one if…” verdict based on fit, not hype. We don't name a flat winner because the right choice depends entirely on your child.

We compare how each one teaches, not what each one charges — prices change, and a stale figure of ours helps nobody.

Ours is included. Every subject, every child on your account, no per-book or per-child fee — and that covers the planner, the subject tutors and your state's records too. Most curricula are bought one subject at a time, per child, every year.
