Teaching Teachers: Number Sense for Common Core

This was a training I did for our 3rd Grade Teachers. I hope it is helpful for anyone out there who has to try to inspire teachers to dig deep and really get third graders to understand number sense. Or for any teachers who want to truly understand what number sense really is. If you have any questions, please let me know. When I presented this, I shared my Mental Math Strategies, Hullabaloo at the Zoo, I can posters, and Monster Problem Solving sets. This presentation does include a simplified set of I can posters. Math is MARVELOUS! I hope you can catch the common core fever!
