All day today Nancy George and Jan Keenoy are leading Integrating Technology Tools in Math to Meet Common Core State Standards today in the tele. The workshop was for math teachers at all grade levels who want to understand the Missouri Core Academic Standards (CAS) for Math and how to tie technology tools into their teaching.  Nancy and Jan, along with the participants, explored the foundation for the standards, the learning progressions, and the major shifts in content, instruction and assessment, along with the technology tools that students need to be successful. What was your biggest a-ha moment from the day?
