Quizizz is a free formative assessment tool which lets you generate multiple choice, checkbox, fill in the blank, poll and open-ended questions and play them synchronously and asynchronously.
EdPuzzle is a free web service and cross platform app which allows language teachers to test students’ listening comprehension skills in and out of the classroom. Teachers can insert multiple-choice questions into clips from YouTube and other video sharing sites as well as teacher-produced clips and have them marked automatically. Students watch the clips and every time a marker appears in the video, they are prompted to answer a question before being able to carry on.
