Textbook giant Houghton-Mifflin has aligned its math books with federal “Common Core” standards. The books are selling well even though, as Twitchy founder/CEO Michelle Malkin demonstrated today, they are replete with jargon and mistakes.

To get a flavor of what the books are like, a good place to start is the publisher’s website:


Even a math teacher wasn’t able to decipher Houghton Mifflin’s gibberish:

Punctuation and spelling errors on the website are easy to fix, and Houghton Mifflin was quick to assure Malkin that it will do so:

But Malkin was just getting started. It turns out that Malkin’s 7th-grade daughter is using Houghton Mifflin’s slickly-produced Algebra 1 textbook, which contains even more jargon and errors than Houghton Mifflin’s website.

Yes, the textbook authors misspelled the word “principal.”

Malkin was careful to distinguish between the old Saxon books, which were excellent, and the new version published by Houghton Mifflin in 2009 (more than a decade after John Saxon’s death):

This is what the new book, which is crap, looks like:

Saxon Algebra 1

This is what the old book, which is outstanding, looks like:

algebra 1

Houghton Mifflin offered Malkin the opportunity to discuss the matter further, but has yet to acknowledge any of the errors Malkin documented:
