This activity allows students to practice solving single step algebraic expressions. It is set up to be played in a way that is very similar to the traditional "telephone" game. Students are given a value for a variable and will solve an equation and pass along the "new value" to the next student in line. This activity can be adopted for small groups or the whole class.
The teacher must come up with the first value of the variable and then check to make sure that the final answer is correct as well. This cooperative activity is a great way to let students practice their mental math skills or to work out short problems on a white board.
