A personal critique form I use with my elementary students. (I've used it with 3rd-5th grade)
Simply write the criteria that you want the students to assess on the board. They copy the item (up to 4) on the lines and then circle a smiley for Yes, Almost or No.
There is also a space for the student to write what they learned from the project and other info they can share.
You can comment or assess on the same page if you want.
