GD&T can lower costs by reducing waste parts, and increasing uniformity, completeness and interchangeability of parts in manufacturing. GD&T is a topic that employers consistently request that undergraduate students know and understand, both at graduation and during undergraduate summer internships and coops, as early as the summer after their first year. GD&T can be a particularly tricky topic to teach due to its complexity, breadth of information, required spatial reasoning, and, commonly, lack of prior exposure to the topic. To assist students in developing spatial understanding, GD&T at a basic level has been developed for a first year undergraduate engineering CAD, sketching, and visualization course, including a set of hands-on demonstration tools and an interactive activity. This paper describes those tools and how to make your own set, along with some suggested activities to help students engage with and retain the concepts. The tools can be made with inexpensive materials, requiring only clear plastic sheets (PVC, acrylic, etc.), clear tape, permanent marker, and colored paper. These activities and materials have been used in a course with 9 sections of 50 students each, which indicates appropriateness and feasibility for classes of a similar scale.  \nI. Introduction  \nAlthough engineering students specialize in a variety of specialized areas, one essential part of the curriculum is learning and understanding measuring and modeling techniques that express the relationship between objects and space. Being able to visualize and conceptualize objects in 3-dimensional space is a skill that is critical to success in STEM coursework and retention in engineering programs over time [1] .
