A small group of children line up on the school playground and the leader in front says, “Simon says, take one small step forward." All the children in a horizontal line a few yards away follow the instructions. “Simon says, take two large steps to the left,” says the leader. All the other children take two large steps to the left. Then comes another command...and a response...and so on. Playing a simple game? Yes. Learning computer coding? You bet. Who knew that playing simple games on the playground is also computer coding? “There are a couple different things that we can do with our pre-readers and some of it is what we call unplugged coding,” explained Timothy Cone, Georgia Tech-Savannah's Center for Education Integrating Science, Mathematics, and Computing (CEISMC) program director.
