MathTwister is a brand new competitive card game for kids (eight years and older) to practice and enjoy the four basic computations of arithmetic. Educators and parents observe their students thinking, organizing and self-correcting their mental math concepts to form equations, as well as watching as students encourage others to demonstrate their math ability. MathTwister makes effective practice of mathematics fun. "Through a healthy level of competition MathTwister gets kids thinking mathematically, challenging them at their own ability level, sharpening fluency with basic arithmetic operations and developing comfort with numbers," Benjamin Bosley, creator of MathTwister, told TDmonthly. Launch date: October 2011.
