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.
The lesson can be incorporated into the study of maths, english, design technology, art & design and computing. The material can be adapted for ages 8-16. The curriculum is aligned to ISTE, NGSS, CCSS and UK National Curriculum standards. A comprehensive list of standards met is included in the lesson platform.

Self-Paced Learning Option
PrintLab's student portal is home to the online learning resources required for each of PrintLab’s lesson plans (CAD tutorial videos, explainer videos etc), but it is also structured in such a way that gives users the option to work through each project online in a self-paced manner without a teacher/instructor. The perfect solution for distance learning, 3D printing clubs, passion projects or self-paced learning at libraries and makerspaces.
