The Common core is indeed crazy....at least in 5th grade. There is estimation questions as appeared in the above post, but crazy ways to multiply, subtract and divide. Not the traditional methods at all. .
These are govt schools and govt can't do anything right. Doesn't even want to do anything right.
Our public schools at one time were some of the best on earth! Government made us one of the most educated nations on earth.
Every last one of the top 20 most educated nations have government ran schools.(Japan, South Korea, Norway, etc)
It isn't the concept of government running our schools that is the problem...The problem is the people that have taken over government that expect such a low standard of things. Why and how do we fix this should be what is debatable.
