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.
Put rice in 5 different solo cups then you can make the that way as well also our kids had fun with putting them back in 10 min every day my two older ones separated the rice and they glued it to page (Bottle Bag Sensory Play)
