Most parents assume their kid is falling behind in Algebra 1/2 because they're "not a math person" or not trying hard enough. After coaching high schoolers through this exact stretch, I'd bet against that almost every time.

What actually happens: algebra is the first math class that's cumulative in a way arithmetic never was. Miss the week you learn factoring, and suddenly quadratics make zero sense a month later — not because the student got dumber, but because one load-bearing brick is missing and everything after it is stacked on air.

Schools move at a fixed pace regardless of whether that brick got laid. There's no built-in mechanism to go back and patch a 15-minute gap from six weeks ago. So the gap compounds silently until a test grade makes it visible — and by then it looks like a much bigger problem than it is.

The fix isn't more homework or a generic tutor who reteaches the whole chapter. It's finding the specific missing brick and rebuilding from there — usually a 20-30 minute fix, not a semester-long one.

That's the whole premise behind what I'm building at Mathletic: weekly 1-on-1 coaching focused on finding and patching those specific gaps for 9th-10th graders, before report cards force the issue. If you're a parent watching a grade slide and can't figure out why, it's very likely a findable gap — not a motivation problem.
