What the data show:  6 years of "Math Investigations" brought Greece CSD NY to Dead Last in elementary math performance among 17 suburban school districts in Monroe County NY.  Similarly it dropped to 3d from last in middle school performance   - But the publisher calls this "evidence for success"... and so does PWCS.   - Notably, the current PWCS Superintendent was the Greece CSD Superintendent during the implementation of MI and the plummet in math performance using this curriculum
