Sum What Dice OR Shut The Box

Please, during this time of shut down, self isolating, don't try and replicate the classroom at home!  What we as parents and grandparents need to do is find activities that have underlying thinking/problem solving requirements but can also be fun for you and the children.

You may already have a number of these activities at home already
               Monopoly
               Chinese Checkers
               Dominoes
               Uno
               Various playing card games.

If not, I will endeavour to post a new activity each day for you to download, and that fits my criteria of
               Enjoyable
               Problem Solving/Thinking
               Repeatable
               A Mathematics flavour (or underlying skills
               Can often be played cooperatively.

The first one I share used to be available commercially as "Shut The Box" but was adapted by Lawrence Hall of Science in the book "Family Math" and called "Sum What Dice". 
My tweak to the activity is below.
