The students will visit this link (https://www-k6.thinkcentral.com) and login with their Google Username and Password. I would suggest selecting the "Remember my school" box so students do not need to select from the drop down menu each time they login:
Username: d25 NAME 4-digits @student.sd25.org (Example: d25Paul1234@student.sd25.org)
Password: sd25 _ _ _ _ (Example: sd25abcd)
In addition, for those wanting extra skills practice at home, I recommend subscribing to IXL: www.ixl.com/ My niece uses it at home and it has helped her review skills very nicely over time.
