What are those drawing paper boards called

[Four]

There are these things where you can write on by putting pressure, and by lifting the paper it clears. I really want one to like write ideas & scratch work and stuff down and quickly erase it.

I used to have one a long time ago and looking for it again

The drawing paper boards you are referring to are commonly known as "dry erase boards" or "whiteboards." They are made of a smooth, non-porous material that allows for writing with dry erase markers and easy erasing with a dry cloth or eraser. These boards are commonly used in classrooms, offices, and other settings for brainstorming, note-taking, and other purposes that require quick and easy writing and erasing. I would recommend purchasing one for your desired purpose of writing ideas and scratch work, as they are a convenient and efficient tool for such tasks.
