I taught kindergarten for 16 years and was a district k-1 strategist for 2. I have a masters degree in curriculum and instruction from Dallas Baptist and a doctorate in early childhood studies with a minor in curriculum and instruction from the University of North Texas. I am currently working for Dallas ISD as a prek instructional specialist.
I just came across a site where teachers can buy and sell original and used teaching materials. There are several membership options. The most basic option is free and only requires online registration. The site is called Teachers Pay Teachers. You can also find them on Facebook at Teachers Pay Teachers.com.
