Objective
Learn to solve Join Change Unknown using a range of numbers.
What You’ll Learn
In this video, we will work through a Join Change Unknown problem.
You’ll also have an opportunity to solve three more JCU problems and reflect on them.

Kimberly Anne Christensen says
Oh my, now I learn there are words that trigger the result. Lol. I am learning a lot but do you have a key that gives hints?
Jessica Boschen says
What kind of key are you looking for?
Christine Watroba says
It would helpful to have a key on how you would solve each problem.
Jessica Boschen says
I’m not sure what you mean by a “key”. For JOIN and SEPARATE problems, you’ll identify the start, change, and result, and which one is unknown. How the problem is solved varies based on what is unknown and how the problem is set up.
Sarah Cedar says
Does the change always include the mathematical operation for the examples used? I am seeing a pattern in my working out..
Jessica B says
I don’t want to say “always”, but yes, you’re seeing the pattern of identifying the change, which is the action in the problem.
