Equality Explorer 2 Variables



This manipulative provides opportunities to:

  • Create scenarios balancing two variables, x and y, with negative or positive values

  • Set the value of the variables and observe what happens to the balance when the values are changed

  • Take snapshots to record past work as long as the manipulative is kept open

  • See an automatically generated equation or inequality that represents the items placed on the balance

PhET also provides translated versions of the simulation in multiple languages, teacher created activities, and with a free account you can access their teaching resources.
