# Teaching math long distance

I have a 13-year-old nephew that liked learning with me, but I've recently moved 400km away. I wonder if it is possible to still learn with him long distance. The subjects I care about are maths and chemistry. We were usually doing additional assignments and puzzles on paper, and I was showing him often, how to write things better (e.g. keep some things vertically aligned) or how to draw an auxiliary drawing for an exercise.

It gets extremally hard when we don't share a piece of paper, so I wanted to invest in a graphical tablet for both of us. I have a few questions.

1. Have you tried such solutions? Do they work?
2. Do we need something with a touchscreen or does a graphical tablet connected to computer suffice? A pad with a stylus is usually significantly cheaper, but I am not sure how hard it is to point to the right thing while looking at a computer screen and writing on a pad. On the other hand, touchscreen solutions are less precise and sometimes annoying for writing.
3. Do you know a "collaborative whiteboard" app or website that we could use as a shared piece of paper?
4. Do you recommend any concrete devices?
• Feynman and a classmate learned rather hard version of quantum mechanics by writing in a notebook and mailing it back and forth. Good luck with the technical selection but I think the human factors (how you stay engaged) will be most important. – guest Sep 4 '18 at 19:44
• @guest I believe times have changed. 13-years-old require now more immediate feedback not to lose attention. He enjoyed learning with me not because he likes math. We enjoyed spending time together and mailing stuff doesn't have the same vibe to it. Playing video games does, but doing puzzles and assignments also had a positive effect on grades :) – tkowal Sep 4 '18 at 19:52
• I think you have to keep the spark of the personal interaction alive. Technology can help, sure. But also, think about the emotional aspect. Distance makes things harder, before and now. You will have to lean into it, to make it work. Good luck... – guest Sep 4 '18 at 19:55
• take a look at Webex and Gotomeeting. I don't know all the details but may match your needs. – guest Sep 5 '18 at 12:39

I have used (and still use) a Huion H420 graphic tablet (it costs around 40$). It has pressure recognition which really helps the software understand and interpret your writing and give a nice output. (Some software does not take pressure recognition into acount and you don't get the full benefit of your tablet in that case). After the first session (say one hour), you should both be pretty much at ease with the way writing works with that tablet. It's like normal writing, except you have to do it in a constrained space, but in my experience, it quickly becomes second-nature so I wouldn't worry about that. The software I liked the most was Microsoft OneNote 2010 (but it also works in Microsoft Word 2010 and I assume more recent versions). I think you can have access to the free online version of these softwares by making a Microsoft account, if you want to try it out. These software recognized the handwritting pretty well. The curves are not converted into rough lines, even if you write really fast, so you don't have to spend 60 seconds writing one sentence or one equation in order for it to be readable. Then it's a matter of finding software to "share-screen". I have used Skype in the past but a downside is that only one screen could be shared at a time (I do not know if this is still the case and if this has been improved). So for example, I could share my screen with someone else, give explanations, but they couldn't show me their work or write on top of what I wrote without me ending my screen sharing and them opening theirs (so it can get tedious if you need to switch often). Things to consider are the synch. Ideally, audio is in synch with video (so that your nephew hears the explanations and sees them written out simultaneously) and your tablet is in synch with your video (for obvious reasons). If your sessions are to last an hour or more, then even a 2 second delay might become annoying. One thing that's happened to me in the past is that I always cut the other person as they were asking questions; all of this due to bad sync (although that was not with Skype). Turning off webcam could help in this situation. Last I checked Skype is also free software so you could try that out today with him and see how your connection is and get a feel for the screen sharing. For example, try to draw things in Paint and ask your nephew if things appear smoothly enough for his taste on his end (does the image refresh fast enough or is it too sloppy). I believe there are some "online whiteboards" that are free can be shared in real-time, but all the ones I found where nowhere near as precise as OneNote was. For example, writing at a fast pace would be perfectly readable in OneNote but complete gibberish using other software. (A$4$might look like a$9\$ because every curve you draw is turned into a rough "line".) I believe there might be two possible causes to this:
