I created a Youtube channel where I plan on going through each trick outlined in my Number Sense Manual. With each video, I’ll go through a single trick with multiple examples detailing how the trick from each section is performed under different circumstances. I plan on adding a few tricks a week, so check back often!
Also, if there are any questions you would like my input on how to solve quickly, please e-mail me at: 
I will reply via a Youtube video which I think might be more helpful than my usual e-mail responses!
Finally, I will keep a rolling list of embedded videos below so that, if you want, you can access the videos from just this website.
Please subscribe to the channel here: Number Sense Tricks Channel
Thanks!
