How many vocabulary words do you need to rescue in unit 4?

Im not sure if your using FLVS, but that's what I use and every unit in english 1 you must rescue 5 words. If your not on FLVS, you must be more specific. If you are on FLVS, for future reference, just read the first lesson in every unit, it will give you this answer along with other info about the unit you are on.
