Games are a competitive environment that engage students and focus their attention on educational goals and specific topics by simplifying content to match learning outcomes. While games risk students becoming too competitive or focused on winning, they can be used in a variety of classroom settings if modified to avoid limitations. Examples include TV-show style games, puzzle games, board games and computer games, which can teach lessons if modified from their original form. Teachers can integrate games by using them to review facts, practice vocabulary, teach counting and money, and as a drill-and-practice strategy.
