Our 7th and 8th grade Project Lead The Way (PLTW) Gateway to Technology students are designing and building wooden puzzle cubes. The cubes must consist of 27 wooden blocks divided into 5 puzzle pieces. Two of the puzzle pieces need to be made up of 6 blocks. The rest of the pieces need to be determined using using a tree diagram. Students used the Engineering Design Process and produced multiview sketches and CAD (computer-aided design) sketches. Solve time statistics were collected and compared (adults vs. kids). Which group do you think will be better at solving the puzzles?
