What is Quizlet?
Quizlet is an online cue card application where students and teachers can create cue cards to work through a learn from, allowing them to access it on any device. I found that this works a lot better when the students are the ones to make their own Quizlet as it encourages them to pick through the material and find key concepts or words that they think they will need help in understanding. They can then use the app when they are waiting for the bus, right before class, as a quick review time with their friends, etc.
There is also a Quizlet plus option that allows students to create and work through tougher questions that require explanations and problem solving.
