For each type of Join problem, I’ve created a slide deck with 10 ready-to-customize Numberless Word Problems. If you want to edit the slides, all you have to do is download or make a copy of the slide deck.

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.
