Might not work full time, but substitute teaching is a good side gig. Plus every school district is desperate for substitutes right now. In the Dallas area, most school districts just require a college degree to become a sub. No teaching skills required. They don't expect you to actually teach, they usually just leave busy work or a video and a worksheet. You take attendance, give them the busy work, keep them somewhat quiet, and at the end of the day you've made $100. Could lead to a long term sub gig (21+ day assignment) which could lead to an emergency/alternative Texas teacher certification and a full-time teaching position if you really had the passion for it. Dallas area full-time teachers usually have starting salaries around $55,000.
