Famous quotes containing the words dial and/or plan:

    “Nods from the Gilded pointers—
    Nods from the Seconds slim—
    Decades of Arrogance between
    The Dial life—
    And Him—”
    —Emily Dickinson (1830–1886)

    “Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.”
    —James L. Hymes, Jr. (20th century)
