Algebra by DragonBox covers the following algebraic concepts: * Addition * Division * Multiplication Recommended for age five and up, Kahoot! Algebra by DragonBox gives young learners the opportunity to get familiar with the basics of equation solving. Kahoot! Algebra by DragonBox uses a novel pedagogical method based on discovery and experimentation. Players learn how to solve equations in a playful and colorful game environment where they are encouraged to experiment and use creative skills. By manipulating cards and trying to isolate the DragonBox on one side of the game board, the player gradually learns the operations required to isolate X on one side of an equation. Little by little, the cards are replaced with numbers and variables, revealing the addition, division and multiplication operators the player has been learning throughout the game. Playing does not require any supervision, although parents can assist children in transferring acquired skills into solving equations on paper. It is a great game for parents to play with their kids and can also give them an opportunity to freshen up their own math skills. DragonBox was developed by former math teacher Jean-Baptiste Huynh and has been recognized as an outstanding example of game-based learning. As a result, DragonBox games have formed the basis of an extensive research project by the Center For Game Science at the University of Washington.
