Engage Students in Each Other’s Ideas: (counting collections)

What do you think about this idea? Take turns counting the collection…take a picture of the first person’s count…the second person counts and leaves their collection out.  Compare the picture of the 1^st count to the 2^nd count.  What’s the same?  Different? 

How could this work remotely?
