I had the opportunity to work on this. I let my son try the demo last week. Hours afterward at dinner I asked him to explain binary to my wife.

"Mom, imagine you have the number 101 in binary. The first 1 is the fours spot, so you have 4. There's none in the twos spot. and 1 in the ones spot. So that means you have 5."

Two days later he came into my office and asked if he could do more tutor.

That's a huge win in my book!

I’ve taught math at the college level for 25 years. The video looked impressive. Do you know up to what level of math it does?

Further down the page, they have a "Curriculum roadmap", which goes up to things like "College Algebra" and "Matrix Theory".

How does that compare to Khan Academy?

[rahimnathwani]

How it's similar:

- focused on mastery

- good treatment of math

How it's different:

- doesn't cover elementary school topics

- lessons are text, not video

- paid, not free

- lessons are presented based on what you already know (e.g. you can't choose to study a topic before you've demonstrated mastery of all topics it depends on)

- I pick the next lesson from a very small set (usually 5 options, sometimes fewer), so there's no wasting time choosing what to study next

- really great spaced repetition system that prevents forgetting

Thanks for the head’s up.

$50/month is pretty steep for what looks like a Khan clone.

It is accredited though. College credit?

[aoki]

They don't grant degrees or diplomas. As such it is presumably accredited as a Supplementary Education Program and (like JHU CTY, Stanford ULO, and AoPS) do not grant credit. Such programs can be the basis of credits if your "real" high school accepts them, though.

We plan on having math through age 10 by the end of the year
