I will frequently use NoRedInk to help introduce and to reinforce grammar and writing skills. Students can access assignments or practice independently by using their school email account to log in.
Quizizz is a great site to practice skills in virtually any subject area — even pop culture and mixed trivia. Students may use their school email addresses to sign in and access quizzes I have assigned or search the site’s library to find quizzes in areas they want to practice.
Quizlet offers practice on a variety of topics in a myriad of subject areas. I may assign study sets that can be accessed by students using the link and logging in with their school email account, but the site is also good for independent practice.
