In 2018, I made the cross-country trip to attend and present at the OAME Annual conference in Toronto. The session was attended by a particularly boisterous group of math teachers–all of whom I adore. Emerging as the ringleader of this rag-tag group of pedagogical hooligans was Fawn Nguyen, who, in her notorious brilliance, later distilled the ideas into a classroom routine by the name “Oops, I forgot…“–OIF, for short. This post is in response to requests to elaborate a touch on the idea and provide more support for teachers thinking about implementing it in their practice.
Been doing “Oops, I forgot” (OIF) routines. I haven’t seen any T do this other than @NatBanting at his session.
Write 2 fractions that =1. Then, OIF, the denominators need to be diff…OIF, 1 denominator is 2-digit, etc.
It has layers [literally] that I really like.
