More about Join problems

This problem type involves situations where quantities are joined together through some direct or implicit action in the situation.

Join problems contain the following elements:

  • A starting amount
  • One or more change amounts that cause an increase
  • An ending amount

While the action of joining is often associated with the operation of addition, addition is not necessarily the operation needed to solve a Join problem. If the start or change is unknown, for example, then addition OR subtraction may be successfully used to represent the situation and/or determine the unknown quantity.
