I didn't say Common Core was used by other countries, I said it was based on methods from other countries. From the Common Core website (http://www.corestandards.org/Math/):
These new standards build on the best of high-quality math standards from states across the country. They also draw on the most important international models for mathematical practice, as well as research and input from numerous sources, including state departments of education, scholars, assessment developers, professional organizations, educators, parents and students, and members of the public.
No, from my understanding, CC math does not adopt math teaching methods from other countries. It is from "reform math".
That's not what Integrated Math is, it blends Algebra, Geometry and Trig together rather than teaching them discretely.
For example, under CC 8th grade guideline. In integrated math, teachers introduce linear equation first. Before students get familiar with linear equation, teachers introduce geometry and statistics. Then teachers ask students to apply linear equations to solve geometry and statistics. For me, I really do not think that is a good way.
I have yet to see large enough reasons as to why these changes are so detrimental. Lack of supplies and teaching experience is a concern, but not something that is insurmountable.
One reason why I got so pissed is that my kid got pushed very fast at 5th grade. Because of CC requirement, my kid need to learn the same material again at 6th grade. If you google more about reform math, you will not feel optimistically about CC math. Also google about NY state CC math and read their response.
I always think CC math is wrong from the quite beginning. The biggest problem for US math education is not curriculum, it is lack of practice.
