Ok, I really took the plunge and started a Youtube Channel that will detail each and every trick outlined in my wildly successful (and free!) Number Sense Tricks Manual.
Please subscribe to the Channel here:
Number Sense Tricks Youtube Channel
I view the videos as a supplement to the Number Sense Manual whereas I will describe less the derivation of each trick and outline more the general thought process when applying the trick under different circumstances. I think having the videos and the Manual sets me a part from other Mental Math channels as you can get exposed to each trick through the Manual, look up the video to see how it can be applied, and go back to the Manual for extra practice.
Anyways, I hope to go through all the tricks by the end of this year. Additionally, I would love to answer student’s questions through videos, so if you have any particular questions you’d like to see answered, e-mail me at:
