Computer-based games developed by the Center for Advanced Technology in Schools (CATS): Improving students' knowledge of pre-algebra topics, specifically fractions and rational numbers.

The CATS-developed video games are a set of educational games designed to improve students' knowledge of pre-algebra topics, specifically fractions and rational numbers. The games were developed through a process of knowledge specification, software design and testing, teacher professional development, and assessment development. The games were designed to accommodate complex and diverse approaches to learning processes and outcomes, and to provide appropriate feedback, scaffolding, and adaptive challenge. The games were implemented in a classroom setting, with students playing each game in a prescribed sequence for a set number of periods. Teachers received professional development training on how to integrate the games into their curriculum, and provided feedback on the games during the training session. The games were designed to be engaging and interactive, with the goal of increasing students' enjoyment and motivation to learn pre-algebra concepts.
