These posters will allow your students to easily monitor their understanding of any concept. This is a great way for teachers to see how students are feeling about their skills and abilities, letting teachers adapt their instruction and interventions accordingly.
I refer to these posters multiple times every single day in my classroom. To rate themselves, I often have my students write their level on their dry-erase boards or a sheet of paper. I also have them hold up their fingers to show what level they feel like they are at.
