When your resume is too long, you can shorten it in several ways. You can try formatting it differently to lessen the white space between sections and in the borders of the pages, or try being more concise. Use bullet points instead of long sentences. If you leave the skills section off of your resume, then make sure to address your skills and relevant qualities in your resume summary and work experience section. For a teaching job, recruiters will be looking to see a variety of hard and soft skills.
