Persuasion Map – “An interactive graphic organizer that enables students to map out their arguments for a persuasive essay or debate. Students begin by determining their goal or thesis. They then identify three reasons to support their argument, and three facts or examples to validate each reason. The map graphic in the upper right-hand corner allows students to move around the map, instead of having to work in a linear fashion. The finished map can be saved, e-mailed, or printed.”
