Summary

This digital resource features profiles for each of the Measurement League: Guardians of the SI superheroes, dedicated to the fight against uncertainty, imprecision, and inaccuracy and to improving the quality of our lives and the things we build. The superheroes include the following: Mole, Professor Second, Monsieur Kilogram, Ms. Ampere, Dr. Kelvin, Meter Man, and Candela. Each card in the set lists a different superhero’s name, picture, symbol, and the measurement unit they represent. The card set provides an entertaining way to learn more about the International System of Units (SI).

Did you know that you can obtain a free set of metric education resources for use in your classroom? Contact the NIST Metric Program at TheSI [at] nist.gov (TheSI[at]nist[dot]gov) and include your name, school, subject, grade level, phone number, and U.S. mailing address. Publication requests may also be made using the OWM Contacts System. The NIST SI Teacher Kit contains a curated collection of instructional measurement resources. A metric conversion card is a valuable tool for science, technology, engineering, art, and math (STEAM) classrooms.

Learning Objectives

  • Describe the seven SI base units.
  • Recognize SI base unit definitions.

Materials

  • Digital file.

Safety

  • Use caution when handling paper edges and scissors to prevent injury.

Teaching Tips

  • Use the Top 10 Tips for Teaching the Metric System
    • Make measurements with metric tools. Measurement concepts are meaningfully established through hands-on activities. Application, not memorization, is the key to success! The SI is easy to learn when taught using metric tools. 
    • Practice building proficiency and confidence in making measurements. Measurement involves doing.
    • Develop reference points. How long? How big? How small? It’s important for students to gradually develop an intuitive feeling for the magnitude of commonly used metric units, including the millimeter (mm) and centimeter (cm). 
    • Use an interdisciplinary approach. Bring the SI into classrooms at every opportunity, including during instruction in language arts, fine arts, social sciences, industrial arts, vocational technologies, consumer studies, and physical fitness. 
  • Explain the SI base units, unit definitions, and prefixes
  • Discuss how each base unit is derived from a combination of defining constants.
