NY & MA 4th Grade Math Curriculum

The next step for our HFOSS class is to develop a educational game for a 4th grade student. The game should be running on a XO laptop, supported by the One Laptop per Child program. Our current task is to analyze the math curriculum for 4th graders in both NY and MA.

In order to correctly analyze the curricula and design the game, we will have to answer the following questions:

• Among the two curricula, how are they the same?
• Among the two curricula, how are they different?
• Which one of the topics would you prefer to implement?
• How will you implement the topic you choose?

Below are the links to the curricula:
MA - 4th grade curriculum
NY - 4th grade curriculum

Among the two curricula, how are they the same?

• Both the introductions are exactly the same (3 major topics, examples, and even wording)
• Eight Mathematical Practices
• Grade 4 Overview
• 4.OA: Operations and Algebraic Thinking
• 4.NBT: Numbers and Operations in Base Ten
• 4.NF: Numbers and Operations - Fractions
• 4.MD: Measurement and Data
• 4.G: Geometry

Among the two curricula, how are they different?

• 4.NBT: MA curriculum additionally requires 4th grade students to know multiplication tables and corresponding division up to 12 x 12.
• 4.NF: NY curriculum additionally expect 4th grade students to know fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12 and 100.

Which one of the topics would you prefer to implement?

• "Understand decimal notation for fractions, and compare decimal fractions"

How will you implement the topic you choose?

• My initial thought would be to have students compare a set of fraction numbers to a set of decimal numbers. This includes converting, equaling, > or <, and possibly rounding.
• Will implement multiplayer mode if the device allows.
