This pdf includes a mistake sheet I made specifically for HS math, as well as 2 accompanying item analysis sheets for students to go problem by problem through their work identifying and correcting their errors. This would be appropriate for all levels of high school math and most likely grades 7/8. It is all written in clear, student-friendly language. The mistake sheet can also serve as a poster or part of a bulletin board in your class. These resources help build up a growth mindset by helping students learn how to reflect on their work and learn from their mistakes. They are especially powerful to use with students who make many silly mistakes.
I use this sheet every time I give a test in high school math. It includes space for students to identify each mistake they made, correct it, and reflect on how to prevent making the same type of mistake again. There is an additional page that features a table describing the most common types of mistakes in math. These mistakes are grouped into 4 categories, with 2 additional columns labeled "what I did" and "how I can prevent it." This sheet can also serve as a classroom poster - I have mine printed on red paper, laminated, and hanging up by as part of our class data bulletin board.
