This bundle (1 teacher instruction document and the 3 documents you use in class) is what I love to use in my class when we finish projects but don't have time to formally present. We "set up" our gallery and use this bundle get awesome feed back while we learn about a variety of topics.
Many grades could use this (increase or decrease time given depending on age) as I've used this with middle schoolers, our ELD classes, and many Special Education and Resource classes. This can be used for any subject or project that I can think of.
For my classes (of around 30 students) it takes about 45 minutes to set up and do this activity, but you could easily add more time or even shorten it if you hustle.
