Common Core Costs to Districts Just Beginning

Where will districts find the money to implement Common Core standards?

I received an email from a Missouri teacher about the increased cost of materials in one school district due to Common Core mandates.

This is an example of the increased cost of curricula mandated by CCSS.  How can the districts absorb these type of costs in the reality of shrinking budgets and revenues?  The teacher writes about the books now aligned to the CCSS standards as opposed to the MO standards.  Keep in mind this is only one set of curricula aligned to the CCSS that teachers must now use.  

The books I use are called Buckle Down.  They are MAP prep resources aligned to the MO GLE standards.  Last year, they cost $7-$8 per student.  The new ones are called common core coach and they are $17.49 per student.  Our budgets are not able to support this increase!  www.buckledown.com is the site.
