**Convention of arrows: the yellow arrows are the math impacts of the MMU1 and the brown arrows are of the MMU 2/3 and the orange for MMU 0.5.**

### Chart 1: in the big city districts, how charters are gaining in math compared to the traditional districts.

Firstly, in this chart, we can see the overall distributions of most large USA city districts’ math gains between the traditional districts vs. the charters vs. MMU x.x variations. 1 year gain of math (which is roughly where Boston, the top charter city) in MMU x.x series is roughly equivalent to MMU 0.2.

### Chart 2: in the big city districts, you can see how far the cities’ maths are behind their state average (by Standard Deviation or by years of learning) vs. how charters are gaining in math compared to the traditional districts.

### Chart 3: in the big city districts, you can see the Nation’s Report Card math results (2015) vs. how the MMU series will impact to the cities if implemented.

MMU 2/3 or 1 impacts on the major city districts if implemented quickly (with the reform time of about 1-2 years), using the NAEP math data of 2015

High charter share big cities’s proficiency shares and how MMU 2/3 or 1 can boost their math over 1-2 years of super fast reforms if there are supports and collaborations
