As a teacher for 17 years, I've always had mixed feelings about sites that ask others to buy content you created. But this year, I've decided that if I am sharing my content with others, if they can afford to help me reimburse my time, or think I have provided a service worth paying for, then I won't refuse.
Most of the money used will probably be used for actual coffee...and if not it's used for supplies and snacks for my classroom. I teach mainly at-risk youth who struggle every day with food insecurities.
If you like what I create, and are able, please donate. If not, I hope this makes your teaching year a little easier.
