In this creative project, students will develop their spatial and mathematical relationship skills before designing a tactile tangram puzzle for people with visual impairments. The lesson beings by providing context about tangram puzzles in a class presentation that features interactive activities. Students then go on to define a user and specific design criteria, before using CAD tutorial videos to assist them in developing models for 3D printing. Once 3D printed, puzzles are tested and iterated upon by simulating visual impairments. Finally, instructions and rules are created so that sighted users can read them to visual impairment players.
