Ideally your student has access to a device, such as a touchscreen computer, Microsoft Surface, or iPad, which supports student writing with a stylus or Apple Pencil. (Note: Chromebooks do not allow annotation on Zoom and are not recommended.)

If your student does not have access to a computer that has a stylus, a small graphics tablet that works with their existing laptop is a great option.  Many of our students use the “One by Wacom” drawing tablet that connects via USB.  (Available on amazon for $49.99

OTHER IDEAS: Without a way to write on the screen, here are some other ways for your student to share their work online.

  • If the student is logged into Zoom on their computer, a separate iPhone or iPad can be used to show student work using camera, photos, or screen sharing (see below for instructions*).
  • A document camera (such as the Hue HD) which can capture and share student’s written work on paper.
  • A whiteboard or notebook which the student can hold up to the screen (analog, but effective!)
  • A mouse will work but is not recommended as the only tool.  It can be very difficult to “write” on the computer with just a mouse.  

Virtual Classroom

Learn math from anywhere!

Prime Numbers is now offering tutoring exclusively online through our Virtual Classroom.  Interactive one-on-one virtual sessions with our experienced instructors are highly effective for learning and provide a personal connection between teacher and student.


Online sessions use an interactive whiteboard so the instructor and student can collaborate and share their work.  Communication between the instructor and student is done via Zoom which provides video and audio.  The instructor and student can both share documents or screens as well.  We can access and share interactive online curriculum, virtual manipulatives and activities, practice worksheets, online graphing calculators, and more!

We use Zoom as our video conference platform (  Zoom enables video, audio, and screen sharing between the instructor and the student.  Zoom also has an interactive whiteboard and allows for the instructor and/or student to annotate anything on the screen.

The first time a student joins a meeting on Zoom, they will be prompted to download the Zoom platform.  If you want to download this in advance, follow this link: and download the “Zoom Client for Meetings.”  There is no charge to the student for Zoom and they will not need to set up a Zoom account. 

The student will receive a link to each meeting upon scheduling.  

Students should join the meeting a few minutes in advance of the scheduled time and wait for the instructor to admit you to the meeting.  Here’s a link for more information about how to join a meeting on Zoom:

If you want to set up a time to practice joining a meeting and testing your tech setup, just reach out.  We’ll do a quick trial run!


-Please ensure students are set up in a quiet workspace with limited distractions.

-Be aware of what can be viewed in the background behind you.

-Headphones can be very helpful to block out noise and help you concentrate.

-Be prepared to learn.  Have your materials available.

*Using an iPhone or iPad to share student work:

METHOD 1.  From the Zoom desktop app, share screen, choose iPhone/iPad.  (The first time, you will need to install a plug-in and confirm that your device is on the same WiFi network as your computer.)  Swipe down from the top right corner of your device and select "Screen Mirroring".  Select Zoom to start sharing.  Navigate to Camera or Photos.

METHOD 2.  Join the meeting from your desktop as usual.  On the iPhone/iPad, download & open the Zoom app.  Share screen with Zoom (type in the meeting ID).  Navigate to Camera or Photos. 

METHOD 3.  Join the meeting from your desktop as usual.  On the iPhone/iPad, download & open the Zoom app.  Join meeting with Zoom (type in the meeting ID).  Share content > Photos > Select photo.


1  Computer/laptop/tablet/iPad with a webcam and microphone.  Cameras and microphones are required to be turned on during the session.

2  Reliable internet access.

3  Annotation capability HIGHLY RECOMMENDED.  A stylus or graphics tablet to allow digital writing so students can show their work during the session. Writing on the screen allows students and instructors to interact directly with the work and significantly enhances virtual instruction.
