Editing Marks Lesson Plan

Instructor: Sharon Linde

Sharon has a Masters of Science in Mathematics

Students often struggle with proofreading, but you can help with this interactive and engaging lesson plan. Students will watch a video lesson to learn why we proofread, then use a text lesson to guide them through the editing marks.

Learning Objectives

After this lesson, students will be able to:

  • explain what proofreading is and why it is important
  • identify and describe the proofreading and editing marks
  • use proofreading and editing marks correctly in text


1 - 1.5 hours

Warm-Up and Preparation

  • Show students a piece of writing with several mistakes in grammar, spelling, punctuation, etc.
  • Ask them to try to identify the mistakes silently, then call on students to share answers.
  • Discuss:
    • How often do you make or find mistakes like this in your or others' writing?
    • What strategies do you use to avoid these errors?
  • Share with students that there are standard proofreading and editing processes and marks to use and allow them to share their own prior experiences.
  • Now start the video lesson What is Proofreading? - Definition & Symbols and pause at 1:31.
  • Define 'proofreading' with students and ask:
    • Why is it important for us to proofread?
  • Play the remainder of the lesson and ask students to talk to a partner about what types of mistakes to look for. Share and discuss answers, then take the quiz.
