Mix & Match Makerspace Challenges - Worlds of Learning | Into the Driver's Seat | Scoop.it
I have been searching for a tool to help me create mix & match makerspace challenges, in the same vein.  I finally found one that I love!  The tool is called Flippity, and amongst other things, it allows you to easily turn a Google spreadsheet into a random Mix & Match grid.  Here is an example of a finished Mix & Match grid that you can demo.  Clicking on the double arrows underneath each column you see, allows you to shuffle each column.  

Using Flippity, I created a few different makerspace challenge Mix & Match grids for you to be able to see exactly how this tool might work for your makerspace!
