Abstract: This video segment, from a third grade mathematics class in Michigan, shows a little less than four minutes out of a longer discussion on a set of conjectures about even and odd numbers. Central here are the pupils’ efforts to prove something in mathematics. In the episode, Jeannie explains that she and her partner, Sheena, have been working together on Betsy’s conjecture (an odd number plus an odd number equals an even number) but they could not find an example where the conjecture was not true. So, she explains, they then tried “to prove that you can't prove that Betsy’s conjecture always works.” Jeannie explains their reasoning and the class goes on to discuss their ideas about proof.

Description:
* The BetsyProof-Start video is a short segment that can be viewed as a streaming video (see the “via BlueStream” link below). In addition, background information about the lesson and video, a transcript of the video, and the teachers’ notes and reflections on the lesson are included below as pdf downloads. * INQUIRIES/USES: This footage comes from an actual third grade classroom and was collected as part of an NSF funded project (TPE-8954724). Although we cannot make the digital video available as a download here, you may request a copy for particular uses. Specifically, our agreements with students’ families and our institutional review board that oversees the protection of human research subjects allow the video to be used in ongoing, interactive work with pre-service and practicing teachers or other educators. Other uses, such as materials development efforts, research studies, presentations, as well as other types of educational uses require special permission.
