Concept/Content
direct measurement with non-standard units (non-uniform and uniform)
Elaboration
- Non-uniform units are not consistent in size (e.g., children’s hands, pencils); uniform units are consistent in size (e.g., interlocking cubes, standard paper clips).
- understanding the importance of using a baseline for direct comparison in linear measurement
- using multiple copies of a unit
- iterating a single unit for measuring (e.g., to measure the length of a string with only one cube, a student iterates the cube over and over, keeping track of how many cubes long the string is)
- tiling an area
- rope knots at intervals
- using body parts to measure
- book: An Anishnaabe Look at Measurement, by Rhonda Hopkins and Robin King-Stonefish (strongnations.com/store/item_display.php?i=3494&f=)
- hand/foot tracing for mitten/moccasin making
