Investigating Interdimensional Relationships

  • Investigating Interdimensional Relationships

    Fifth and sixth graders examine connections during three key activities: watching and discussing Flatland: The Movie, constructing four-dimensional models, and working with arithmetic and geometric patterns.
    The phrase interdimensional relationships may conjure images of UFOs, alien beings, wormholes, and even mystical powers. These notions of interdimensionality were not out of bounds in the middle school learners’ experiences described in this article. However, these notions do not entirely capture the mathematical relationships investigated with my former fifth and sixth graders. These students questioned the idea of dimension when given opportunities to “play” with spatial phenomena.
