Regarding letter writer Tony DiStefano's perceptive comments about the Common Core curriculum, I would add that the obvious cracks in this structure should make parents worried about the education leadership that thought this was a good idea to inflict on families and communities ("Common Core isn't ready for prime time," Oct. 1).

Children should never have to ride a plane that is being built as it flies. An engineer or airline who tried such a stunt would be jailed for child abuse.

The consequences for the children who are thrust into a shaky curriculum at the hands of flustered, untrained teachers are likely to last a lifetime. Shouldn't those who chose to put children and teachers in such a lousy situation also face stern consequences?
