three fourths
|
When I heard Riba say "three fourths" I wrote "3/4 or 3 fourths?" I
think that she is thinking about 3 of her fourths, which are groups of
4.
She knew that "one half" of 6 was not 1 group of two, but doesn't seemed
to have linked her understanding of "one half" to the notation "1/2".
Will making that link help her to interpret "3/4" as 3 out of 4 groups?
Or does she first need to develop an understanding of "one fourth" as
1 of 4 equal groups?
