What I have a problem with is when the course is (allegedly) about real world problems yet there is no mathematical development. No theory of quantity. I especially have a problem when the title of the course is "Algebra". It never bothered me before when they titled the course "Math for Daily Living".
And let me add. These alleged real world problem courses get so screwed up because the authors think like Dehaene. They think there is some magical innate sense that is being suppressed and can be released if we would only stop teaching the math and let the children discover it on their own. With calculators.
"The calculator is like a road map for the number line. Give a calculator to a five-year-old, and you will teach him how to make friends with numbers instead of despising them. There are so many fascinating regularities to be discovered about arithmetic. Even the most elementary of them looks like pure magic to children."

Sort of reminds me of Jehovah's Witnesses keeping medical care from their children.
