Here is another source with a video giving pretty much the same information:
A look inside the math textbooks rejected by Florida | Watch (msn.com)
The link Essentialsaltes gave in the highlighted Popular Information is text and more detailed.
Speaking as a longtime math geek (Back when I was applying to college there were also subject tests associated with the SAT. Math has level 1 and level 2. I scored 800, the highest score possible on math level 2 without any prep) I see huge problems with what seems to be the Florida gross over reaction to social issues being included in math textbooks.
First they say with math there is one right answer. Anyone who made it to quadratic equations knows that is wrong. For a quadratic equation there are typically 2 right answers. At least for problems given. In some cases there is just 1 and for cases when one just picks the numbers at random there are often no solutions, at least if limited to real numbers.
I like there being one or more objective right answers. But I remember that the most common complaint by students is that math is not relevant, i.e. that it has no application to their part of the real world. What Florida seems to be doing is going down a road where textbook producers will shy away from anything that ties math to real issues. On a pure math level that will lead to all word problems being things like 'Johnny is twice as old as Jane, six years ago Johnny was 3 times as old as Jane. How old is Jane'. The huge problem is that when word problems are limited to this or any other set of a few forms students do NOT learn how to translate words into numbers. Instead they learn how to follow a pre defined path and turn the crank. And NOT just the students who are weak in math. Those with a gift and liking for math often find out that to do well in class they also have to depend on learning how to turn that crank, because it is faster and tests almost always involve time limits. (Note that I would have been an exception. I was fast, very fast, I typically finished math tests very early, so no bitter grapes issue. I just happen to occasionally care about others, something it seems is evil as far as Florida is concerned,).
Frankly what is being done will be a disaster for math education. It will turn math into something that even more students hate, even students who could have grown to like math. And it will leave those who still manage to like or love math less prepared for the higher level math that they will need if they want to proceed in any of the sciences.
It also seems that there is some degree of opposition to making students show their work. One get's the right answer of 2 times 2 equals 4 when they do not know the difference between times and plus. Often with easier problems a good math student can simply see the answer or do some simple calculations to zero in on it. That will not work for harder problems. Thus the easy problems which should have prepared the student for more difficult ones fail to do so. Sadly most teachers do a poor job of explaining this. In a the answer is all that counts environment that will only get worse.
Of course, this is good news for students from other states who will gain a significant advantage over students under-educated in Florida.
