Famous quotes containing the words places and/or decimal:

    All places are distant from heaven alike.
    Robert Burton (1577–1640)

    It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.
    David Elkind (20th century)
