I agree, John. At one solstice the EoT is about +2 minutes, and at the other it is about -2 minutes so there would be only a slight discrepancy. Too small to worry about, especially as this is a junior school project and Judith is trying to avoid too much complicated explanation.
I like her approach for its simplicity, but there's one potential problem which I don't know how to solve. What happens if the summer dot is on the ceiling and the winter dot is on a wall? How do you draw the straight line connection? I can imagine the method being used by other teachers in the future, and people forgetting to take back Daylight Saving Time for the summer labels, or vice versa.
