90 Minutes on a Sunday Afternoon or: The Proof of the Special MT Issue Is in...
Direct linkDirect link
Pinel, Adrian – Mathematics Teaching, 2002
This article was written as a result of the author reading "MT177," a special issue dedicated to the teaching of "proof" in mathematics. He used the ideas in this special issue for planning his session "mathematical reasoning and proof," which was part of a weekend course for primary trainees. It consisted of three activities: (1) How many…
