#099 Topics in Depth: Angles and parallel lines with Jo Morgan (supported by TES)

Something different from this episode of the Mr Barton Maths Podcast.

This is the second episode in the Topics in Depth series, with me and Jo Morgan. Following on from Episode 1 on Indices, this time we go super into in the world of Angles, looking at measuring, labelling, angle facts and more.

For the last few years I have at engrossed through several Topic in Depth presentations given by Jo. In these she takes a mathematical topic and describes how she approaches planning, sharing resources, approaches and quirks from the past and the present, as well as discussing common misconceptions and how we might tackle them.

I have been eager to find a way to get these out to a wider audience, so we have partnered with TES to make this happen.

The following discussion was filmed, and to get the full experience you probably want to watch it as you can see first-hand the resources that Jo is describing. Our idea is that these videos might be watched by individual teachers to aid their planning, or even whole maths departments to stimulate discussion.

The PowerPoints:
Angles in straight lines and triangle
Angles in parallel lines

Thanks so much for listening, and I really hope you enjoy the show!

  1. hi Craig,
    with teaching supplementary… students could view each letter ‘P’ as a backwards digit 9 … think of each as 90 degrees. therefore two letter P in this word = 180 degrees.

    Complementary has one letter P therefore the two angles sum to 90 degrees.

    this only works if the teacher spells the word correctly in a test. eg : “identify a pair of supplementary angles in the given diagram”
