This study aims to investigate mathematics teacher educators’ (MTE) knowledge in noticing preservice teachers’ pedagogical content (PCK) on the hierarchical classification of quadrilateral. A multiple case was conducted analyze responses ten MTEs an online moderated-forum group discussion (M-FGD) from their written work MTE-PCK test completed prior M-FGD.

Results show indicate considerations classification: by definition properties quadrilaterals visual appearance quadrilaterals. Despite this, 20% them were indicated perform lack understanding quadrilaterals, invalid flowcharts validating
