After introducing your students to these Invisible Dumbbell Stations, play this Kahoot by Patricia Fiorelli in small groups! This is a great way to utilize your Chromebooks.
You can, also, apply the idea submitted by Adam Mullis and have students play in partners where they have one student see the question and run down to a student who cannot see the screen and tell them which color is the correct answer. Then, the other partner runs to where they can view the screen for the next question.
