MathScaled is a prototype series of puzzles based on a balance-scale format. The goal is to place different shapes with unknown weights on the scale so that it is balanced. Puzzles have embedded supports for solving, such as a Scratch Pad for recording information and the option for immediate feedback on your progress. Learners can also choose from different levels of puzzle challenge.

These puzzles were developed as part of the iSolveIt project at CAST (http://www.cast.org), an educational research & development organization that works to expand learning opportunities for all individuals through Universal Design for Learning (UDL). iSolveIt is being developed as a mobile digital learning environment to support the development of logical thinking and reasoning skills, essential competencies for algebra and mathematics in general.
