Code.org provides several options for device free/unplugged coding activities.   This is a create way to reinforce the critical thinking and problem solving needed to complete coding activities.  This list is extensive, so we have suggested a couple of our favorites:

• Unspotted Bugs- elementary (40 min)

• Binary Images- upper elementary (40 min)

Kodable also provides options for unplugged coding lessons.  These are hands-on, problem-solving activities for students.   This list provides worksheet options as well as problem-solving lessons. They are organized by grade level so it is easy to find a grade level appropriate option.
