"Sacrificial" fence

I need to make a rabbet cut on a piece of plywood and am planning on using the dado set to do that. My plan is to clamp a board to the fence to protect it from the blade, a “sacrificial fence” as some describe it. However, I seem to remember an alternative method to achieve the same goal that was pointed out to me while I was getting “checked out” on the table saw. I can’t remember the details of this technique specifically, so if there is such a technique and someone could jog my memory about how it works, I’d appreciate it.

Thank you.

There is a sacrificial fence already. It’s a white melamine board to the right of the saw, against the wall. It has some holes to pass clamps through to attach it to the fence.

Great! Thank you very much.
