These posters are great to post on the wall for your kids to reference as you complete a quick and easy informal check. I'm constantly asking my kids to rate themselves 1-4, and it's easy to do with these posters.
There are 4 levels, which say the following:
Level 1- I need some help. I don't understand it at all.
Level 2- I'm starting to understand, but still need help.
Level 3- I understand the skill, and can do it independently.
Level 4- I can teach it t someone else because I understand.
