Use Class Tools

This page is for teachers. If you are an administrator, go to Set up Class Tools.

During Class Tools sessions, you can share learning resources with students as well as use live translatable captions on ChromeOS devices to keep your students focused and engaged.

Requirements

  • Class Tools is available only on ChromeOS devices with ChromeOS version 137 or later that are enrolled in your school’s Google Workspace account. Teachers and students who use their own personal unmanaged ChromeOS devices can’t use Class Tools.
  • [Preferred, but not required] In Google Classroom, you have created a class that contains the students that you plan to use Class Tools with. For tips and tutorials on using Google Classroom, visit the Classroom Help Center. Here are some suggestions to get you started:

Start a Class Tools session

Step 1: Launch Class Tools

  1. Sign in to your ChromeOS device with your teacher account.
  2. Launch Class Tools, either from the ChromeOS device shelf or app launcher. The Class Tools app automatically opens in teacher mode and displays the Start new session page on your screen. If this is your first time using Class Tools, you’ll be presented with a feature tour.

Step 2: Connect to students

Google Classroom

To connect with students through Google Classroom, you must be using Google Classroom and have classes already set up. Otherwise, follow the instructions to invite students using a unique join code.

  1. On the Start new session page, click Students.
  2. At the top right of the Students page, click Add students.
  3. From the list of classes that are available to you, find and click the class that you want.
  4. A list of students that are part of the class roster displays. To include all students in the class roster, leave the Select all box checked. Otherwise, to include only some of the students, uncheck the Select all box and select the individual students that you want to connect to.
    Note: It’s important that you deselect students that are not present for the in-class session. Otherwise, you might interfere with their current activity on their device. For example, they might be absent due to illness or working with another teacher instead.
  5. Click Add X students, where X is the number of students you want to add.
  6. To add students from other class rosters, repeat steps 2 to 5.
  7. Next to Students, click  to go back to the Start new session page.

Join code

If you don’t use Google Classroom or have students present that are not part of a class roster, they can still join a Class Tools session. You can invite them by sharing a unique join code that is generated once the session has started.

  1. After you start the session, you’ll see the Join code on the Session in progress page. You can share the code using copy and paste, or open it up into its own window in large font.
  2. On their ChromeOS devices, students launch Class Tools and enter the unique join code that you shared with them.

Step 3: Choose learning resources that you want to share with students

  1. On the Start new session page, click Resources.
  2. At the top right of the Resources page, click Add resources.
  3. Choose an option:
    • Classroom assignmentsAvailable only if students have been added via Google Classroom. Select resources that already exist in Google Classroom for the class. When you’ve selected all of the classroom assignments that you want to share, click, Add X assignments, where X is the number of assignments you want to add.
    • Open tabs— To include all the open Chrome tabs in a specific window on your ChromeOS device, check the Chrome Window box. Otherwise, to include only some of your open tabs, ensure that the Chrome Window box is unchecked and choose the individual open tabs that you want. When you’ve selected all of the open tabs that you want to share, click, Add X tabs, where X is the number of tabs you want to add.
    • Links - Enter the URLs that you want to share during the session. You can add a list of URLs using copy and paste. Click Add another link to add additional URLs. When you’ve added all of the URLs that you want to share, click, Add X links, where X is the number of URLs you want to add.
      Note: Be sure to supply correct URLs—Enter the fully qualified domain name. For example, enter google.com, not google.com.
  4. Configure navigation restrictions

On the Session in progress page, click Students and follow the steps to connect to students. Similarly, you can remove students from a session, if needed.

You can add learning resources to a session while it’s in progress. On the Session in progress page, click Resources and follow the steps to share resources with students. Similarly, you can remove resources from a session, if needed.

Pause (or lock) student devices

If you need your students' attention during a session and want to temporarily prevent them from interacting with their ChromeOS devices, you can temporarily lock their devices. Captions and translations remain visible to students, even when their device is locked.

On the Session in progress page, click Pause devices. Students’ screens immediately lock—There is no lock countdown.

When you’re ready to let students resume working on their devices, click Pause devices again.

View student screens

During a session, you can view students’ screens from your own device, allowing you to keep an eye on individual students’ progress throughout the session. Keeping privacy in mind, students are notified before you view their screens.

  1. On the Session in progress page, click Students.
  2. Find the student that you want to view.
  3. Under the student’s name, you’ll see which live tab is currently open on their device.

    A window opens showing the student's screen, Students are notified before their screen is viewed.
  5. To stop viewing, click Click View screen image again.

The student experience

Starting a session

When you start a session, Class Tools automatically opens in student mode on student devices. They can see session details, including session name, teacher name, and time remaining. Students can also view and navigate the resources that you shared with them.

Limited use of device during session

If you’ve turned on Only allow Class Tools, Class Tools is in full screen mode and students can’t view content outside of Class Tools. For example, students can’t see or use their ChromeOS device shelf, app launcher, settings, and so on. Students can navigate the resources you shared as well as view captions and translations, but nothing else.
Note: Using Class Tools in teacher mode, you can change the Only allow Class Tools setting at any time during the session.

Captions and translations

If you allow students to use captions, they can turn on and off captions themselves, as needed. Similarly, if you allow students to translate captions, they can choose their preferred language in the transcript box.

Customize and move the Captions and translations box around the screen

The transcript box is flexible for students—They can resize it, move it around the screen, and customize its appearance by changing the font size and color, as well as adjusting the background color. For information about how to customize captions on ChromeOS devices, go to Use captions on your Chromebook.
