After students have collected all their evidence and determined it's relevance (using the Evidence Log), they will then sort their evidence. They will be ranking 6 pieces of evidence. They can either choose their top 3 "yes" pieces and their top 3 "no" pieces, or they can choose 6 "yes" pieces or 6 "no" pieces.
The purpose here is to start thinking of the strength of each piece of evidence. Their goal is to convince someone that the claim they choose is the "right" claim so they need strong and convincing evidence. Here they will defend their evidence and explain why it is the strongest or why it is not very strong.
