A complete presentation with all the visuals for introducing Binary conversions. Instructions written by a CS teacher who has performed magic for more than 40 years. The magic trick is fool proof and requires no special talents other than being able to add and subtract. Masters are provided for the manipulatives in three different sizes including one that can be handed out to the students to push their reasoning ability. The trick hooks their attention and you move to a visual presentation that establishes conversions in a most visual way.

The presentation has step by step instructions for not one but two ways to perform the magic. Unlike most magic tricks, this one can truly be repeated over and over and 99% of the sharpest students will never figure out how you do it. Perfect way to make that lifetime type memory. Also included is an Excel file to make the visuals as large as you are able to print.

New Masters in Excel format provided - previous flaw on two cards.
