One of the things a mentor told me, early on in my career, was "I should not be doing more work in the classroom than my students. It is the students' education, so they should be doing the work." That was the greatest tip I learned in 20 years of teaching. How did I go from taking home papers every night, talking so much my voice gave out, and wearing out my shoes and my body from being on my feet too long? First, I cut my content lessons down to 15 minutes. Many students cannot sit still and pay attention longer than that. Second, all of their content "practice" was done in cooperative groups using "high yield learning strategies". (Look for the high yield strategies on the Instruction page.) They did the learning and creating. I no longer had to spend all my plan time copying worksheets that my students hated. Third, I never took grades on practice work because students were just starting to learn the material. Would you like it if someone gave you a grade on what you learned during a PD session? The only grades that I took were a review page/activity (that the students graded themselves) and a test (that I would take home to grade or grade during my plan time. Remember, your plan time is for planning lessons, entering grades, copying papers, meeting with team members, etc. (With HS, this would be different. They are required to have three grades in a week so they might take a homework review page for a grade.)
