Online teaching
Hello!

I have started teaching mathematics online due to the current situation and am looking for resources. My students range from primary school (8 years old) to secondary school (18 years old). I have quite a few books but it's time consuming to scan pages and send them to students, so I'm looking for electronic versions.

I am looking for books on precalculus and calculus to supplement the textbooks we are using.

Also, any recommendations on hardware to enable drawing graphs and mathematical symbols? I'm using efofex on my laptop to draw during lessons (via Zoom). Efofex is great software but I think a pen would give me greater freedom and speed. I've seen the special pens and tablets but I've never used them.

Hi Nad!

Easy to find calculus books in pdf format on the web, just google it!

For pocket calculators you can find Stuart's calculus addendum to TI-83/84 and for TI-89/92 here:
Stewart Calculus (TI-83/84) and Stewart Calculus (TI-89/92)

We (me and my daughter) are using XP-Pen Deco 03 tablet with AutoDesk SketchBook for simple tasks and for screen recordings with OBS Studio, like this mechanical engineering video (screenshot here):

   

Or Krita for more advanced drawings or animations:

   

Sketchbook and Krita totally free softwares.

For on-screen calculations I recommend to use emulators, this is a HP forum, but must to know, the TI extended their emulators availability for an email registration here: TI emulators

I prefer for middle school and BSc video tutorials the TI-30X Pro Mathprint (mainly mechanical engineering not mathematics), for more complex requirements maybe better to use TI-84 series or jump to Python, if required to program little projects.
Yesterday just for test I tried a Lorenz attractor on TI-84 emulator, it was approx. 5 minutes from scratch, very easy to learn and it is possible to save/load programs and data from/to PC and the old TI-83 programs runs also:

   

The CASIO's emulators also available, my personal experiment with it, their emulators are too slow on PC, very easy to miss a keystroke.


I hope this helps.

RE: Online teaching
Hello Csaba!

Thank you very much for the helpful tips. The TI emulator is excellent and several of my younger students who don't own a CAS calculator have installed it.

Online teaching presents a number of challenges but also has its benefits. For example, I can silence the whole class at the touch of a button!
