It’s the first Monday of the new semester. Over Christmas Break, I had the privilege of having an awesome lunch with some amazing local math teacher tweeps. Shelli mentioned that she missed my regular Monday Must Reads posts. So, I’m hoping to do a better job this semester of keeping up with sharing your twitter awesomeness here on this blog. Hopefully this will also help me stay more engaged on Twitter this semester.
