Cubelets are awesome little cubes that are either inputs or outputs. Each combination of different cubes creates a different robot. I use an inquiry-based approach when introducing my students to these little robots. I just give them and go over the first two pages of this packet or pages 3-4 of this packet. First, students predict what each Cubelet does based on what it looks like or its color (some are very hard). Then, they are to investigate and take notes on the function of each Cubele
