Class code is a unique identifier generated automatically when a new class is created, whether imported from Google Classroom, Clever, or added manually. This code allows students to join a specific class by entering it when prompted on their account’s home page.

If you need to add more students to a class imported from Google or Clever:

Option 1: Go to the "Classes" page and click Sync to update the class list with any new students.
Option 2: Have the student create their own account using Google, Clever, or a username, then join the class by entering the class code. Students can do this by selecting Join a Class from their homepage.

To delete or edit a class, go to the Classes section and select Edit or delete class under the class name. Here, you can rename the class, update the grade level, or remove it entirely.

There’s no limit to the number of students or classes you can add to your teacher account.

You can locate and add 99math by searching for it in the Clever library.

You can share assignments directly from your 99math account to Google Classroom. After creating an assignment, choose the option to share it with Google Classroom, allowing students to access the game directly from their Google Classroom dashboard.

Assignments will stay visible to students for up to 2 weeks, unless you set a shorter deadline. After completing an assignment, students can continue to practice it. In your teacher reports, you can track how many times a student has attempted the assignment and see their highest score.

Reports are generated only for completed Live games or Individual assignments. If a Live game is ended before all rounds are completed, a report will not be created. For example, if you play 2 out of 3 rounds and leave the game, no report will be saved in the Reports section.

Students may appear twice if they join an assignment using a game link or code without logging in. To prevent duplicate entries in the report, remind students to log into their accounts before completing assignments.

To add a co-teacher, go to the “Classes” section in your 99math account. Click the “Add co-teachers” button. Co-teachers must first create a 99math account to be added. You can add up to 4 co-teachers, and they will be able to see all game reports for the class.

In the Classes section, you can manage student features such as friend requests and nicknames:

Friend requests: Allow students to connect with classmates or restrict this option to only in-class connections.
Nicknames: Allow students to create and use nicknames during Live games, or restrict this to keep full names displayed.

Follow these steps to create a Group game:

Log into your 99math account, and select Start Now on the main view.
On the left side, select a grade level or Math Facts skill category.
Choose a specific skill to practice from the center list.
Adjust game settings on the right side, where you can choose the number of rounds and time per round.
(Optional) Select Custom Game below the grade options if you want more control over specific skills.
Click Play Live to start. You’ll see the game code and lobby, where students can join by entering the code.

You're all set!

The game code appears in the game lobby after you create a game. Share the code with students, who can enter it at the top of their screen. For younger students (Grades 1 and 2), there’s also a QR code option they can scan to join.

There is no maximum number of students for a Group game. As long as you have a good internet connection, an unlimited number of players can join. Note that a minimum of 3 players is required to start the game.

To set a class goal for home practice:

Select Home Practice and follow the steps provided to set up at-home access.
Choose the class from the dropdown list.
In Step 1, you’ll find options to print login information or email access instructions to parents.
In Step 2, set a class goal by choosing the total number of minutes each student should aim to complete at home each week. You can select from preset options or customize the time to fit your class’s needs.
After setting the goal, return to your Dashboard to monitor student progress and check how close they are to meeting the class goal.

To assign practice for individual students:

Go to Home Practice from the left menu.
Click Create Assignment.
Choose a grade level or Math Facts skill and add specific skills by selecting Add.
Set a deadline for the assignment (it will remain visible for two weeks if no deadline is set).
Click Assign to generate a game link, or share directly via Google Classroom. Students will see the assignment in their accounts if assigned to their class, or can join using the game code. To see the game code, click on Show to students.

If students can’t find an assignment in their account:

Have them refresh the page.
Assignments can also be found in their Settings if they close the initial pop-up notification.

Students can change their avatar by either:

Selecting a new one when they join a Live game.
Logging in and clicking on the avatar in the lower-left corner of their main page, or by visiting the shop.

Students can also buy custom avatar items with Mbucks earned from playing at home.
