We're going to throw in a few math lessons here and there, so if math really isn't your thing, free free to just watch the videos and see what you think. All of these lessons require only a brain, and once in awhile paper and pencil, so this area is 'materials-free' and jam-packed with great mathematical content. If you're the parent, stick a calculator in your pocket and test out your kids as they go along.

Some of what we cover here is based on the book "Secrets of Mental Math" by Arthur Benjamin, an incredible professor at Harvey Mudd College. He's also known as the "Lightning Human Calculator". Here's a video about him you may enjoy:

  1. Wow.Amazing!My brother got the dvd for x-mas.

  2. Oh, right – that makes more sense. Yes, that lesson is a great one to start with. Currently, I am working on a HUGE set of math videos to be added, so tackle the ones here now (there aren’t that many), and then you’ll be ready for the big set when it’s released. 🙂

    Hi again, Aurora,

    I think I wasn’t clear in my last question.
    Specifically, we want to learn how to begin to do the mental mathemagic stuff. At the bottom of your description of mental mathemagic is a link that says “first lesson” if you want to get started. When I click on that link, it just takes me to “how to multiply 2 digit numbers by 11.” Is that where the link is suppose to go?

    Thank you!

  4. You can start anywhere you want to on this site by selecting an area of interest here: https://www.sciencelearningspace2.com/study-units/ There’s no particular order, but if you’re new to the site, you’ll also want to watch the intro video here so it makes more sense how to get the most out of the 900+ experiments on this website. You’ll find two videos to do this:

    When I click on “first lesson” my computer takes me to “how to multiply 2 digit numbers by 11”. Is that wehre I was suppose to go or am I missing something?

    I know!

  7. Yes, you are right! I highly recommend his items in the Math Resource section!

    I saw a live lecture by him. He’s amazing! I learned so much from him. He made a dvd course for people. They, as well, are amazing.

    That was so cool.I could never ever do that in my life.He rocks

  10. You’re right – he sure did! He wrote about how he came to love numbers while riding on the bus as a child in his book. I highly recommend his math course (look under math recommendations).

  11. Susan Strydom says:

    Amazing!!! He must have loved Math as a child.
