Some great math exemplars: Guided Math Group Work
Here are some great exemplars. I think it is good to do them in small guided math groups, so you can see what students are doing and they can talk through their approaches. When you are looking at exemplars, you want to notice if the students are meeting the content standard as well as the mathematical practices. Set up some criteria for the students. Practice doing a bunch of exemplars together and then also have the students do them in partners and groups. You want to scaffold the learning and give students a sense of success.
Let me know what you are doing with exemplars:) Do you do them daily, weekly, monthly? Does your school have a plan? Does the grade level have a plan? Do you do exemplars across the content domains? Let me know and send me examples of the great stuff you are doing out there!
