Mathematics Research Talks #9
Solving Subtraction Problems by Means of Indirect Addition: findings from a Collaborative Lesson Research Cycle
Thursday 8 July 2021: 16:00 – 17:00hrs
Subtraction problems of the type a – b = ? can be flexibly solved by various strategies,. This includes the indirect addition strategy (“how much do I have to add to b to get at a?”) which is particularly useful when a and b are close. However, often children do not choose this strategy. Dr Ruth Trundley will explore findings from a collaborative lesson research cycle which expose some of the reasons why this might happen and the challenges associated with addressing this issue.
This talk is FREE to attend.
