Have you seen…this important resource for our teaching?
From researchers at Harvard University and Vanderbilt University, the Compare and Discuss Multiple Strategies (CDMS) routine, and the curriculum materials for algebra courses?
Explore the curriculum materials and learn how to use the resources. See the About page for a summary of the Create & Discuss/Multiple Strategies routine which it is suggested should take about 20 minutes.

Within each resource, you will find questions that could be used for discussion of the example, a “think-pair-share” routine and a “Big Idea” page that summarises the lesson objective for the example.
The teacher’s guide also explains each of the four strategies.

As you can see from the image here you can filter the resources by Type, Lesson Use and Topic, within each topic you will find several subtopics.
Great resources. Looks really useful for intiating discussions among students.
Great Post. The structure of CDMS is a helpful extension of what is often done ad hoc. Gives it clarity. The resources supporting it are helpful and time saving.
