I read "Hop on Pop" to my kids dozens and dozens and dozens of times - along with "Red Fish, Blue Fish" and "The Butter Battle Book." I sometimes still call my youngest (now 18) "My Daisy Head Maisy."

While I usually tutor several hours a week in math, I had about 15 minutes of tutoring an ESL student on an essay a month or so ago. Her assignment was to write a persuasive essay with supporting evidence to support or reject "Designer Babies."
She had been working on the essay for days and had only written half a paragraph on the con side, her supporting evidence being that it is "against god."
I suggested she first write an outline of her paper and made a reference to "Sneetches" which she did not understand. I then recommended she read it. In fact, I think every HS graduate ought to have read it (though I had until years later myself).
