Colfax High School students, with a support of MIT, invented the Tri-Metric.
It is a tool that offers a brand new way to layout a house. The mechanical device sits in the middle of the building envelope and uses similar shapes to make sure the floor, walls and roof are all square to maximize support. This tool can be used by any home builder, but is especially designed for emergency relief housing constructed by Mercy Corps. It can be manufactured for under $20 and because all the complex math of trigonometry is built into this inventive tool, it can be used by the novice, expert or anyone in between.
Watch the amazing progress of these high school STEM students applying academics and using critical thinking throughout the design process. Twenty-three movies are available on the ColfaxMath channel under Colfax Inventeams Tri-Metric.
For example, watch the evolution from prototype to products on Twenty Little Bets to make the Tri-Metric. See how to Learn Trig the easy way with the Tri-Metric. Find out how to use the Tri Metric, Construction Layout Tool.
