What a fun game! Make two dice: one with numbers, and one with colors. Roll the dice, then use dot stamps to make that number of dots in that color on your paper. My adaption would be to have the dice be a doubles dice to practice double math facts
Love this idea for sorting shapes. I would change the shape after they have master the previous shape. Sorting is a huge part of a CDC classroom. They can learn and work on fine motor skills at the same time.
