In this activity, student groups design a new system of measurement. This activity is designed for groups of four students and may be completed quickly if all students participate.
Explain to students that the criteria for developing an effective system of measurement are on the clipboard image.
Emphasize that they should keep these in mind as they create their measurement systems. Their systems will be evaluated on these criteria during their presentations.
Have groups use the space on the next page as a workspace for developing their systems.
Proposed base unit (with scaled units in parentheses)
- Length or distance: the mano (manito, mano, manisimo)
- Volume: the brick (brack, bricky, brick, and the brick-crick)
- Capacity: the gulp (minigulp, gulp, big gulp)
- Mass: the skittle (skittette, skittle, skittanic)
Use the provided templates to help students prepare their presentations.
You may want to provide groups with a larger piece of paper so that more than one student can work on the poster or page simultaneously.
After they have completed their posters or pages, have students practice their presentations.
