Cognitive Coordination Card Challenge
Change 2D symbols on each card to a 3D hand shape. Visual instructions included and thoughtproductionslc.com has game playing examples.
With a digital version of the copyrighted card challenge, you can display each card to a larger number of people at one time and in a larger size than playing cards. Also this eliminates the need to hold the cards by playing in a group flashcard style (#6 on the instruction sheet).
One symbol on each card starts this coordination challenge to decipher with vision and fine motor dexterity.
