We love it when students are thinking and reasoning, and it's important to know how best to build and experience sophisticated strategies. In this episode Pam and Kim continue discussing Dr. Peter Liljedahl's work and finetune where it's appropriate to use vertical nonpermanent surfaces, and what other kind of tasks we should be doing whole class with students.

Talking Points:

• Randomized Groups at Vertical Non Permanent Surfaces in random groups are great for Rich Tasks that follow your curriculum 
• Problem Strings are best used whole class to build specific strategies, models, and big ideas

See Episode 157 for Pam and Kim's introductory comments about Dr. Liljedahl's work.
