With the "Hour of Code" next week, we wanted to get the kindergarten through 6th grade students familiar with coding. We set up a 12 x 12 grid (3x3 feet squares), place obstacle in certain squares and created a type of maze. The object is for the students to get in groups of 2...on will be a "robot" and the other a "programmer". It is the job of the programmer to give verbal only directions to the robot and guide them through the maze the a target on the opposite side. Once they reach the target, the programmer gets a token (made on the laser cutter) and the students switch rolls and start again. For the 3rd-6th grade, we added a degree of difficulty and have the robot blind folded.
It's a kinesthetic activity to help the students understand coding. We followed a StarWars theme (like Hour of Code) and printed various "Darkside" figures on the laser cutter.
