This article is part of Enriching the Secondary Curriculum.
This article contains three videos showing parts of a 75 minute lesson in which a group of Year 9 students (aged 13-14) worked with us on the problem Tilted Squares.
We have written a few bullet points about each video to draw attention to teaching points which we consider to be important.
The first video shows the start of the lesson.
