Goal:
Students
identify common and uncommon measurements and build conversion
tables.
|
|
Grade
Level:
3-8
|
|
Objectives:
- Identify and use correctly various common terms of measurement
- Sort the measurement terms into categories
- Identify some uncommon terms of measurement
- Construct conversion tables for both common and uncommon
terms of measurement.
- Relate measurement to that which is very small and that
which is very large, e.g., atomic particles and astronomical
units.

Procedures:
1.Students
use dictionaries and web sites to research various terms
for measurement.
2. Students classify terms into their uses, i.e., measure
distance, weight, temperature, etc.
3. Students classify terms into functional or vocations
uses, i.e., pharmacists, cooks, computer scientists, astronomers.
4. Students construct table of unusual conversions and measurements.
