I've been really studying preschool curriculum books to figure out different ways to work on fine motor skills... and one of the ways is to have kids peel stickers off of a page and stick them onto a card.
Boring... I thought...
BUT, I did it anyway... and THEY LOVED it ... and it literally kept them occupied for 30 minutes! Talk about fun!
The act of peeling and sticking develops fine motor skills by exercising small muscle groups in fingers in coordination with the eyes. The development of these skills helps preschoolers eventually write, draw, button their buttons, work zippers, etc. Very important skills!
