Hello everyone,

I am interested in helping my son learn mental math. I was planning on starting with Jones Geniuses. However, I have found a Soroban/Abacus class that I want to enroll him in. Should I still buy Jones Geniuses for him? Does it make sense for him to learn both, or would it just cause confusion?

What types of mental math did you try with your children? How were the results?

Thanks!

We did math everyday from age 3.5 on. My son started algebra at 5, calculus at 7. For mental math I suggest "left to right" computation and the book "Secrets of Mental Math" by Arthur Benjamin (available at most libraries). Here are the results:

That is wonderful!!!! My son just turned 5 last week, and he is doing beginning algebra (solving for x in simple addition, subtraction, and multiplication equations). Did your son also learn how to do algebra in more complex equations (multiplication, division, fractions, square roots, etc.)?

I heard many great things about that book. I heard that many parents taught from that book rather than investing in Jones Geniuses. However, I'm not sure if I should just let him go to a Soroban class, or if I should have him learn both Soroban and Jones Geniuses. I'm not sure if it's sensible for him to learn two different ways to do mental math.

Thank you for your response! That is an amazing video of your son!!!

We have just started learning and we are using this book http://iranischool.com/file_cms/Secrets-of-Mental-Math-Guidebook.pdf . For now, both parents and kids are interested.
