Important aspects about teaching the idea of units
What are seen as the units used for these numbers (quantities,
figures)? It is important to ensure that students look for the units
(constituent elements) and their relationships that they need to
focus on.
Furthermore, one must consider which unit to use, as in the
case where tentative units can be used to examine a Width. In
the case of “3/4 is what number times 2/3?,” 1/4 and 1/3 are the
units. The children must be made to see the need to “look for
the units” and furthermore to “try changing units to something
easy to compare, While considering What should be changed to
the same unit (fraction).”
