Palo Alto does indeed use the "Investigations" series in, but it is heavily supplemented with the previously adopted textbooks (Holt, Math Unlimited). Detailed cross-correlation were developed by the staff in recognition of the deficient content in Investigations.

So are the "state and national tests" that districts using "Investigations" get good scores on, indicative of the quality of "Investigations", as they do not prepare children for their future? Just curious :-)

I expect that many readers are already aware that the "mile wide and an inch deep" slogan, while catchy and initially heavily promoted by TIMSS in the US, turned out to be unsupported by a more detailed evidence from TIMSS. I believe it is rarely used anymore by TIMSS staff.
