math enrichment & support

Prime Numbers Virtual Classroom

Prime Numbers is now open for in-person classes and tutoring.  However, we’re happy to report that we will continue to offer virtual support options to our students.   Private tutoring, pairs tutoring, and some small group classes will be offered through our Virtual Classroom.


Online sessions use an interactive whiteboard so the instructor and student can collaborate and share their math 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 online curriculum, practice worksheets, online graphing calculators, and more!


-A computer/laptop/tablet/iPad with a webcam and microphone.
-Reliable internet access


Ideally each student has a way to show their written math work during the lesson.  A stylus or graphics tablet is strongly recommended for the best interactive learning experience.  Here are some ideas to consider:

-A device (such as a touchscreen computer, Microsoft Surface, or iPad) which supports the student writing with a stylus or Apple Pencil.

-A graphics tablet (we recommend the "One by Wacom" available on amazon for $39.99) which connects via USB to facilitate digital handwriting.

-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 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.  

Students may want to wear headphones (or a headset with microphone) during the session to block out noise and improve concentration.


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.

Be prepared to learn math.  Have your math spiral, some graph paper, a pencil, and your calculator available.


We use a video conference platform called Zoom ( .  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 the meeting via email.  For weekly meetings, a recurring link will be used to connect each time.


Let us know which email address is best to send the link.

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!

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.
