Kmath or Brighterly
Live lessons help with tonight's homework. Kmath finds out why your child is stuck.
Both are for parents worried about math. They do two different jobs. Here is the honest difference, price included.
$69 assessment once, then $100 - $260 per student, per month.
The short version
Two different jobs
Brighterly
A live teacher on a screen, usually two 45-minute lessons a week, K to 10, math and reading.
Kmath
An assessment that finds the exact idea your child got confused about, then a printed workbook every week to fix it, with a guide for you in your language. No appointment.

Is it more expensive?
Yes. Here is what the difference buys.
About $142 a month is less than $100 - $260 per student, per month. What it buys is about 90 minutes a week with a person, which helps with homework stuck tonight. What it usually does not do is find the skill from two grades back that is quietly breaking everything.
What does Kmath do instead?
Find it, fix it, prove it
Find the cause first
21 questions. Each wrong answer points to the exact mistake and the grade it started in. Not "weak in fractions": the actual wrong idea.
Fix it a little at a time
A printed workbook every week. Part closes the old gap, part follows the class, part starts next week's topic early.
Keep you in it
Every workbook comes with a guide for you, in your language: what to say and what to ask.
Prove it
Short check-ins during the week and the full assessment again every 4 weeks. A gap counts as fixed only when the assessment shows it.
If you do not speak English at home
The part written for you is in your language
With Kmath, your reports, weekly guide, emails and website are in Spanish, French, Haitian Creole or Brazilian Portuguese. If you have ever been handed a school report you could not fully read, you know why that matters.
So which one?
Pick by what your child needs
Brighterly
If your child mostly needs a person to sit with them through homework and keep them going each week.
Kmath
If your child has struggled for a while, nobody has told you why, and you want the reason found, fixed on paper and proven, and you want to understand it too, in your language.
Common questions
Is Brighterly cheaper?
Yes. About $142 a month against Kmath's $100 - $260. They also offer a free first lesson. Kmath charges $69 once for the assessment that finds the problem.
Is there a live teacher with Kmath?
No. No appointment. You get a printed workbook each week built from your child's assessment, and a guide that tells you how to help.
Can I do both?
Some families do. The assessment names the exact broken skill, which is useful even if someone else works on it with your child.
Do I need to be good at math?
No. The guide tells you what to say and what to ask, and the answer key checks the work.
