This is a very simplified version of the card game Spot It! Just print and cut. You'll need 1 deck of 13 cards for every 2 students. I recommend marking the backs with different colors or something to keep the decks straight. I'm including a simple instructional video I made for my students. They really got into it.
This can also be used as a template for other items (exactly 13 different numbers/pictures/etc. are necessary). If you do make your own Spot It, please send me the link through PM. I would like to check it out. Thanks.
