The game/trick that I want to share is one that I learned from my dad. The trick involves creating a series of flash cards each representing a place value of binary numbers. If I wasn't having technical difficulties, I would show these digitally, but I'm nit sure how to do so on my phone, so I am instead linking a description of the trick and will explain verbally on Monday.

Love this game -- I used to play it as a child, and then eventually came to understand how it works. Good explanation!
