Audience ?
The Common Core demands that students engage in much higher level problem solving than many have experienced before.
The Standards for Mathematical Practice (SMPs) are the heart of the Common Core and all our activities should move towards working thoroughly with them.
In my classroom:In my classroom: started experimenting school-wide initiative deeper problem solving process:
o read problems togethero whole-class discussiono work together: pairs or groups
of 3o individual write-up for HWo class presentations
Scholars’ Challenge AScholars’ Challenge A
1. Make sense of problems and persevere in
solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the
reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated
reasoning.

Lessons and Results• Our test scores as a school improved on the open-
response section of the state test.
• While students initially had a hard time, they became much more comfortable with the process over the course of the year.
• Students felt great satisfaction when they did well on problems.
• It is important that all students have an entry point to the problem. Students shut down when problems were too hard.
• This year, I am focusing on using more open-ended problems that will allow students to develop strategies for reasoning and proof.
