These clips are from a lesson using What type of triangle? The clips may help you prepare to use the resource or reflect on classroom practice.
These students kindly agreed to let us film them sharing their initial thoughts as they worked on this task. Our aim in selecting these classroom video clips is to offer an opportunity to see the different ways mathematical thinking is revealed, as it plays out, rather than as a final and polished piece of work.
After viewing each clip
Spend a minute replaying the clip in your mind. Try to reconstruct significant parts of the episode. If watching with a colleague, compare your accounts of what you saw — watch the clip again if necessary to reach agreement.
Consider the prompts relating to student thinking and the teacher’s role.
Try to relate these episodes to your own classroom experience.

What does each clip reveal about these students’ understanding of coordinate geometry and triangles?
As a teacher, what choices might you make in a similar situation in your own classroom?
Teacher reflections

Here the teacher shares her thoughts on the lesson and how the students responded to the task. This is part of a longer interview with this teacher and a colleague. You can see further clips from this interview and classroom video in the Resources in action pages for Distance between points (a related resource) and Inverse integrals. |

We are very grateful to these students and their teachers for allowing us to film them working on What type of triangle? and the subsequent discussion.
We are grateful to Julian Marshall for directing the filming, selecting and editing some video clips and for his guidance on the use of classroom video.
