The King’s birthday, potentials for developing mathematics teaching
Résumé
In this paper, we have analysed a video in which a small group of students were asked to find out when the Norwegian King was born given his 80 years of age today on his birthday Feb 21st 2017. We have identified potentials for initiating shifts in discourse in which children’s ways of solving a problem could become an explicit object of reflection. We suggest that revoicing as a talk move to encourage collective reflection, did not work as suggested in the research literature. Additionally, working on a number line could have been a joint activity of making what was previously done in action, to an object of reflection.
