When you initially boot up a Chromebook device, you will see a welcome page. You should see the text "HCS Remote Learni..." in the middle of the screen with an arrow pointing to the right under that text.
Kindergarten through 2nd graders, click on the arrow. Then click on the blue button with the white arrow on it and you will be taken to a web page where you can easily launch Seesaw or Zearn.
Grades 3-12, click on the button at the bottom of the window titled "Add Person" and log into the Chromebook as you always have typing your student number as the first part of your email address.
Parents, remember, you have access to your child's UserID and Password through the MiStar Parent Portal and we have created document that will walk you through the steps to obtain that information. (ParentPortal - Student Network Information)
