Teachers can use Patterns to help students visualize different 3D solids, how they can be transformed, and how to calculate their surface areas and volumes. It can also be used to encourage exploration, creativity, and digital artistry. However, the frame of any work done with Patterns at this point in its development will have to come from teachers and students deciding together how to use the game. That isn't a bad thing at all, but other sandbox games out there (let's just say it: Minecraft) engender more user engagement through more intuitive gameplay. The complexity of Patterns, combined with its lack of helpful constraints or player guidance, may stand in the way of using it for collaborative projects or student-directed learning for novice players.Continue reading Show less
Editor's Note: As of October 2014, Patterns is no longer available for download.
Patterns is a downloadable 3D sandbox game that uses prisms and pyramids to let players sculpt a wide variety of geometric solids. Players control a "triangle man" who explores gorgeously rendered worlds to collect and build with such materials as heartwood, glowing moonstone, and runestone. In the single-player Realistic mode, players must collect all the resources they need and then use the game's crafting tool to build the basic shapes and patterns they want to use on a regular basis. For example, to unlock the cube shape to use with any material, the player has to first craft a cube. Players build large objects out of several smaller objects; they can even approximate spherical objects by building with interlocking pyramids. Multiplayer worlds also exist, as do worlds based on such mini-games as collecting a certain amount of a particular material in a given time frame. Users can also submit and share the worlds they build. The game uses a variety of 3D shapes (including cube- and pyramid-shaped worlds) and beautiful alien graphics to distinguish itself from other sandbox building games.
In the right classroom, Patterns could be great for exploring geometric solids, their surface areas and volumes, and how they can combine into new shapes. The game is in its Genesis (alpha) version, however, so it doesn't play as fluidly as it might in later versions. The camera tries to follow the player dynamically and switches between perspectives, making it difficult for users to focus on building projects as they move. The camera requires frequent right-click adjustments, which makes it painful to play on laptops with trackpads. The "triangle man" protagonist is a bit too alien to identify with, and the lack of a tutorial or any real danger makes it unclear why anyone would play in the Realistic mode of the game -- a user might get crushed by a falling tree but doesn't have to worry about health, hunger, or threatening mobs. Because the game uses so many shapes, figuring out what to build using trial-and-error experiments can be daunting.

Geometric Measurement And Dimension
Give an informal argument for the formulas for the circumference of a circle, area of a circle, volume of a cylinder, pyramid, and cone. Use dissection arguments, Cavalieri’s principle, and informal limit arguments.
(+) Give an informal argument using Cavalieri’s principle for the formulas for the volume of a sphere and other solid figures.
Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems.
Identify the shapes of two-dimensional cross-sections of three- dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Find the volume of a right rectangular prism with fractional edge lengths by packing it with unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would be found by multiplying the edge lengths of the prism. Apply the formulas V = l w h and V = b h to find volumes of right rectangular prisms with fractional edge lengths in the context of solving real-world and mathematical problems.
