Correction to: Teaching interrelated concepts of fraction for understanding and teacher’s pedagogical content knowledge (Mathematics Education Research Journal, (2019), 10.1007/s13394-019-00275-0)

Abstract

The original version of this article unfortunately contained a mistake. The figures in Fig. 2 and Fig. 3 are misplaced. The figure in Fig. 3 is “An example of representing the measure construct of fraction (Siemon et al. 2015)” and should be placed in Fig.2, whereas, the figure in Fig. 2 represents “The operator construct of fraction (Getenet and Callingham 2017)” and should be placed in Fig. 3. The correct versions are given below. The original article has been corrected.
