“Grid Paper Exploration,” by Randy Lomas (Harvest Park Middle School and AIM Math Teachers’ Circle), was recently published in the California Mathematics Council ComMuniCator. In the article, Lomas describes a middle school exploration of a favorite MTC problem that involves counting squares on a sheet of grid paper. Lomas began writing the lesson plan in summer 2015 at the AIM MTC summer immersion workshop, as part of a new program for veteran members of the AIM MTC. Lomas and five other classroom teachers paired up with mathematicians to create lesson plans with a focus on open-ended problem solving. The lesson plans were later classroom-tested by other members of the MTC.
Lomas’ lesson plan and Tatiana Shubin’s MTC session on which it is based can be found in our video library.
