I want some suggestions

[Mamidi Naaresh Reddy]

Iam mathematics facilitator  .I wanna make videos on maths.what kind of white board am I supposed  use .please help me

[Gokul]

Use the board that is "white". Make sure the lighting is proper and audio and video is also good. 

If you can, I suggest you to use graphics tablet and a sketchbook to write and screen recorder to record. It will save you a lot of time and energy.

I use iPad with Apple pencil. Check this video: https://youtu.be/sXrO6fr6MZY

I have recorded the screen as well as my iPhone using a table top stand, super imposed one on another. The result is impressive.

Another option is lightboard. I haven't used it myself, but planning to set up one. Check this video for a demo: https://www.youtube.com/watch?v=L1au1JxMSaA

Hope this helps.
