A self assessment tool for students to fill out. Two self assessment sheets per (A4) page. It is a great size to be glued into a book or so on.
Can be used as a formative or summative assessment tool.
For example, I was teaching a math group multiplication strategies and had them write goals of what sort of questions they wanted to answer in 2 weeks. I used this at the end of the 2 weeks so that they could review their goals and assess their own learning.
