Quizizz is similar to Kahoo!, but I think you and your students will enjoy it more! Your questions and answer choices can be longer in length. The questions appear on your students phone or tablet, as well as your computer screen/smartboard.
You can use Quizizz as a formative assessment tool by utilizing the analysis functions that are available. You can see the questions that the students missed and adjust your teaching to ensure that all students are learning what needs to be learned.
