- What information do you have?
- What do you know that is not stated in the problem?
- What approach are you considering trying first?
- What estimate did you make for the solution?
- In this situation would it be helpful to use..a graph..., number line..., ruler...,diagram...,calculator...,manipulatives?
- Why was it helpful to use...?
- What can using a _______ show us that ________ may not?
- In what situations might it be more informative or helpful to use...?
