A 99math host is the teacher who creates and runs a live math game for their class. Setup takes under two minutes — select a topic, generate a game code, and students join at join.99math.com from any browser. No student accounts or app downloads are needed. This guide covers every step from account creation to reading post-game results.
What Is a 99Math Host?
A 99math host controls the session from a teacher dashboard. You choose a math topic, set the number of rounds and time per round, and decide whether students play solo or in teams. The platform generates questions automatically based on the topic — no manual question entry required.
99math covers grades 1 through 8 with over 1,000 math skills. Students join using a unique code at join.99math.com. The setup works similarly to how a gimkit host manages a session — the teacher controls the game while students interact from their own devices.
How to Create a 99Math Host Account
Go to 99math.com and select the teacher signup option. You can register with an email address or link a Google account. Once inside, the dashboard shows your game history, class data, and settings in one view.
For step-by-step instructions on signing in or creating a new account, the 99math login guide covers the full process. If you plan to track individual students over multiple sessions, set up a class roster from the dashboard before hosting your first game.
Why teachers use 99math host — top reported reasons
Setting Up Your 99Math Host Game Before Class
Good preparation prevents most technical issues during a live session. Here is what to do before students arrive:
- Select a math topic that matches your current lesson — all topics on the platform are reviewed by math teachers.
- Click “Create Game,” then set round count and duration. Live games default to three rounds of 30 seconds each.
- Choose between solo mode, where students solve 50 questions individually, or team mode for group play.
- Share the 99math game code via your classroom screen, LMS, or video call link.
- Run a short test session to confirm all student devices are connecting correctly.
Solo mode works well for homework assignments. Team mode reduces pressure for students who find direct competition stressful.
How to Run the 99Math Host Session Live
Open your game and click Start Game once students appear in the lobby. Display the code on the board or share it through Zoom or Google Meet. Students enter the code at join.99math.com and are in within seconds.
The dashboard updates in real time. You can see who is leading, which questions are producing the most errors, and who is falling behind. After the game, share the leaderboard and acknowledge improvement alongside top scores — not just the winner.
Reading 99Math Host Post-Game Data
The post-game report shows total points per student, accuracy rates, response times, and which questions caused the most errors. Use this to decide what needs review before the next session.
You can add notes for individual students directly from the report page. For additional configuration options, 99math hacks covers team setup tips and session customization methods teachers use to get more out of each game.
