Answer keys are no longer posted due to teacher requests. Apparently, clever students find the answer keys and copy the answers without actually working the problems themselves. If you are one of those clever students, keep in mind that worksheets are designed to help you understand content. Many of my students don't even get grades for doing these exercises as they are intended to help you master the material. In fact, that's really what homework is all about.
That being said, I realize some teachers are busy and some are teaching outside of their subject expertise. I do post answer keys on TpT, for a minimal cost. Proceeds go to support the creation of more resources and site hosting.
