From the submitter:
Students were presented with the photo of the bowl of lilikoi and the story: Brayden and Caelyn picked lilikoi. There were 13 lilikoi in the bowl. Caelyn picked 5 lilikoi. How many lilikoi did Brayden pick? The second photo shows student predictions. If a student changed their mind, we crossed out their previous prediction and wrote the new one.
Give a theory as to why students answered 13 before answering 5 (or 8).
Thanks to Mitzi Hasegawa for the excellent submission.
