However, this term I have been trying to build in more interleaved practice into my lessons, where appropriate. So rather than teach my pupils about the three types of line separately, we tackled them altogether.
Here is my lesson:
It started with the pupils drawing a triangle and marking on an altitude, median and perpendicular bisector and annotating the diagram with the properties of each line. Continue reading
