I'm beginning to think that AI's real threat to education is ending the jobs for which education prepares us.

Essential reading.

Even as McMahon has shrunk the Department of Education, she’s operated in what she calls “a parallel universe” to radically shift how children will learn for years to come. The department’s actions and policies reflect a disdain for public schools and a desire to dismantle that system in favor of a range of other options — private, Christian and virtual schools or homeschooling.

Also do you know about bulk egg cartons, which often carry the label 2 1/2 dozen?

Oh! And some with an 18-egg carton might make for a nice denominator shift, plus an additional unit.

3 eggs are 1/4 dozen, but 1/6 of the carton

not real eggs/cartons but I also used eggs the one time I had to teach fractions

several problems where students have to how many eggs were originally in a case

Also, image search turned up lots of 10 egg cartons. Is there somewhere that is typical? Who has decimal eggs?
