Most of the students do not like taking paper and pen with them to each class (and a lot forgot or lose it along the way) so this is a great tool for them to be able to use! Whether it be for a lecture during class or when they are doing research for a project or new topic.
I also really liked using the Quizlet website! What a fun way for the students to study and review! I especially like the scatter and space race options and the students love using them to practice! I also really like that there isn't an age restriction for sign up since not all of the students that I teach are 13 and older.
