This is something that I found from the help of some students in my content area reading class. This is an app/ website and can be used for a quick formative assessment in your classroom. Students use their phone or tablet and answer from one of the four answers; kind of like multiple choice. Then the teacher can get a graph to see how students did and where they struggled the teacher can to back and review. This only takes a few minutes in the class and you can create your own questions to follow your content!! Kahoot!
