NY and MA Math Curriculum Comparison

How are the NY and MA 4th Grade Math Curriculum Similar?:

Well since the Common core has been implemented, they are virtually the same. They both focus on:

Multi-Digit Multiplication and Division
Dealing with operations in Base 10 up to 1,000,000
Understanding Fractions
Dealing with Measurements and Data
Identifying lines and angles

I really haven't been able to find many differences. In face both seem to be line for line identical save for the following discrepancies:

In MA, students are expected to "Know multiplication facts and related division facts through 12 x 12."

One that seemed an interesting concept to explore with a game was 4.G #2:
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

I thought it may be cool to make a simple matching game but with images of different angles and intersecting lines instead of generic images.
