Do Problem Strings and Thin Slicing achieve the same results? In this episode Pam and Kim discuss the differences between Problem Strings and Dr. Liljedahl's Thin Slicing.

Talking Points:

• Different purposes, different facilitation
• The importance of recording student thinking
• When non-permanent surfaces can be helpful
• Problem Strings are strategically planned sequences and not always 'easy to more complex'
• Differences in the teacher's role, questioning, math relationships
• Word problems are natural extensions of Problem Strings
• Problem Strings and Thin Slicing: Some similarities, but not the same.
