Some Problems of the Week
Here are some great problems of the week to either do as a whole class, in centers or in guided math groups. Remember that you want students to show a model of their thinking and describe a strategy ( a way of thinking about the numbers). They should write about how they solved the problem and check it in a different way than they first solved it.
Remember that when you are teaching problems you should refer to the problem type. The research says if teachers help students to have a conceptual understanding of the problem then they can better solve it.
