I suspect this Arizona story is just a small sampling of what's going on nationwide.
Common Core is an enormous scam on the American public. Pearson, with the help of its political allies, is making millions. Our children are Pearson's unpaid guinea pigs, worker bees, data gold mines, and victims. Americans' tax dollars are being used to victimize their own children in a money making scheme so enormous that it should have the suffix "-gate" after it.
I encourage you to join nationwide groups to get more information about Common Core: Parents and Educators Against Common Core, Left-Right Alliance for Education, Dump Duncan, Common Crud, Badass Parents Association, and Badass Teachers Association are a few of the groups with good information.
