Easy and fun.Velcro + popsicle sticks make for great quiet time or restaurant activity. Put velcro dots on the ends of popsicle sticks. Kids can make letters or shapes over and over again. I found velcro dots at my local dollar store.
Could also be used in a spelling center.Lego-out the words. Lego learning games - exploring Lego and play dough. This is a great activity for sensory play, imaginative play, letter recognition and sight words.
