One of the most important skills for a fabricator: CAD designer, 3D printing, laser cutting, wood worker, skilled trades person, engineering, is being able to accurately measure an object and convert those units. For example, STEM students need to measure object with a ruler or machinist rule and then convert those measurements to decimal inches to enter into CAD or other modeling software. Students also need to be able to convert from standard inches to metric units (mm, cm or m).

In this activity, the instructor calls out a width or height measurement in fractional inches. Students use their rulers or machinist rules to find the tile in their bag of tiles. They convert the fractional inch value to the decimal value to see if that value is on their bingo card. If the measurement is on the card, they cover that space with the tile that matches the called out measurement. First student to get three in a row and calls out "Bingo!" wins!
