Based on a problem solving chart I received at a workshop, I created a journal/notebook style guide to help students fully explain the process of solving an exemplar.
It is Microsoft Word, so you can edit it to fit your students!
UNDERSTAND the problem: "I have to...."
THINK of your plan: "I will... (use this strategy)
SOLVE the problem: "Here is my work."
COMMUNICATE your solution: "This is how I figured out the answer... "The answer is..."
Make a CONNECTION: "Something I noticed is..."
It is colored coded, too! When I copy for my students I have them outline the line in the color specified to check their work or as they go so they don't miss a step!
