# A Geometric Lens

One of the topic areas covered in The Radix Endeavor is geometry, and more specifically modeling with geometry. This can mean building things in the world that are made up of geometric shapes, as well as solving volume and surface area problems by approximating the shape of real-world objects with prisms. We’ve already created a bare-bones prototype and had high school students use it this summer. What we found is that students took the basic prisms the prototype let them create and really ran with them! They created cities and geometric sculptures, and enthusiastically asked each other how to create the cool things they saw on each others’ screens. We loved the potential we saw in this tool and we hope to be able to incorporate this level of creative play in the final version of the game.

While the Radix shape-building toolset will be kept relatively simple, it’s fun to look at other places where spatial thinking and design skills could be applied. The Stata Center building right here at MIT is a real-world example of geometric shapes gone wild. And the delightful images from the Geo A Day blog show that there is no limit to what you can create when you see the world in terms of shapes. This kind of geometric lens on the world is something we strive to provide students who play Radix!

# The Marketplace

One of the earliest pieces of concept art we got from Filament was this image of a marketplace. It was an instant favorite with our team because of the way the colors make it feel both dark and mysterious as well as warm and intriguing. As a player exploring this world, we can’t resist peeking in to see who is behind that curtain and what exotic wares they may have to offer.

At the time, we didn’t know exactly how we would use this setting but we knew we wanted to have a marketplace in the game world. Later, as we were working on the algebra curriculum, we decided on a bartering system for the marketplace that would play up the desire to explore the unique goods on offer there, while creating a place where players will need to think about unit conversions, ratios, and systems of equations. Using math skills in a realistic context, players will be able to get the best deals on their much-needed berbuckles, myzle flowers, and exploding fruit.
