Create a fun learning game in just minutes or choose from thosands of already made games. This works on any device and kids love it. Teachers are presented with good formative assessemnt data at the end of the quiz as well.
Similar to Kahoots. Easy to make new quizzes and large bank of already made quizzes. Integrates very easily with Google Classroom. You can assign homework with it. Automatically saves all data from each quiz that can easily be put into PowerSchool.(Manually) This is my favorite.
Most are familiar with the famous Quizlet flashcards. This is the next generation of that and allows classroom to be automatically divided into teams where they can compete against one and another. As with the other sites in this catagory, you can make your own quiz or use one of the thousands that have been made by others.
A bit different than the above mentioned sites. This is a presentation tool that you can use to not only present information but also assign quick, formative assessment activities. Teacher can create presentation and then present that exact presentation to each students device. Students can then interact with presentation. Looks pretty cool!
