Join Math Future and John Mason Wednesday, February 22: Elastic multiplication
During the event, John Mason led a conversation about multiplication as scaling, as well as answered some questions about his work.
John writes about elastic multiplication: "It is often said that 'multiplication is repeated addition' when what is meant is that 'repeated addition is an instance of multiplication'. I have been developing some tasks which present 'scaling as multiplication' based around familiarity with elastic bands. Participants would benefit from having an elastic (rubber) band to hand which they have cut so as to make a strip; wider is better than thinner if you have a choice."
