Two stars and a wish is a formative assessment strategy that can be used in the class as a peer assessment tool. Students can use this strategy to assess a peers writing piece and can provide constructive feedback. The two stars represent two things the student has done well and the wish represents one thing the student can improve on.
This is a poster that I designed for 7 and 8 year olds but it could also be used in upper primary and high school. It includes four posters. "A star is for..." "Star sentence starters..." "A wish is for..."Wish sentence starters..."
Post these on your classroom wall as a reminder for how to use the formative assessment strategy.
