Audiences: Grades 6-8, Grades 9-12

Primary Subjects: Algebra

Related Topics: addition, algorithm, coefficient, fractions, inverse, multiplication, variable

Students play a generalized version of connect four, gaining the chance to place a piece on the board by solving an algebraic equation. Parameters: Level of difficulty of equations to solve and type of problem. Algebra Four is one of the Interactivate assessment games.
