Reflection: Shared Expectations Making Sense of Surface Area (day 1 of 2) - Section 3: Poster Planning


When I make it clear to my students that I am interested in their ideas and that their ideas are the source of learning they begin to ignore me and look to each other as a source of information. After constantly probing their ideas and putting their questions back to the group they begin to understand that their math family group is responsible for pushing the conversation and the understanding forward. When I approached this group they continued to clarify the meaning of surface area on their own without turning to me for information or confirmation. 

It takes persistence and patience on my part to continue to ask my students:

  • what do you think?
  • why do you think that?
  • what do you think of his/her idea?
  • what does he/she mean by that?
  • how does that help you?
  • why does that make sense?
  • can you show us that?
