Discuss the factors students must consider when choosing the unit with which to measure an object
What will be an ideal response?
Complete answers will include the following: When children see a need for a referent, they are encouraged to choose a variety of units with which to measure the object. The first criterion for selecting an appropriate unit is that it has the same attribute as that to be measured. Thus, a long thin object such as a pencil would be a good unit for measuring length but it would not be a very good unit for measuring area or angles. Another consideration is the size of the unit relative to the object to be measured. The unit should usually be smaller than the object but large enough so that the counting can be completed in a reasonable time and the resulting number has a reasonable magnitude; one would not want to measure the thickness of a page with an eraser or the length of a classroom with a paper clip.
