A complete lesson on the theorem that the angle at the centre is twice the angle at the circumference.
For me, this is definitely the first theorem to teach as it can be derived using ideas pupils have already covered. and then used to derive some of the other theorems.
I will shortly be uploading lessons for the other theorems.
Activities included:
Starter:
A few basic questions to check pupils can find missing angles in triangles.
Main:
A short discovery activity where pupils split the classic diagram for this theorem into isosceles triangles (see cover image).
If you think this could overload pupils, it could be skipped, although I think if they can’t cope with this activity, they’re not ready for circle theorems!
A link to the mathspad free tool for this topic. I hope mathspad don’t mind me putting this link - I will remove it if they do.
A large set of mini-whiteboard questions for pupils to try. These have been designed with a variation element as well as non-examples, to really make sure pupils think about the features of the diagrams.

A complete lesson on perimeter, with a strong problem solving element. Incorporate a set of on-trend-minimally-different questions and several opportunities for pupils to generate their own questions. Also incorporates area elements, to deliberately challenge the misconception of confusing the two properties of area and perimeter.
Activities included:
Starter:
A few basic perimeter questions, to check pupils know what perimeter is.
Main:
Pupils come up with a variety of shapes with the same perimeter, then discuss answers with partners. Designed to get pupils thinking about which answers could be different, and which must be the same.
A slight variation for the next activity - pupils are given diagrams of pentominoes (ie same area) and work out their perimeters. Raises some interesting questions about when perimeter varies, and when it doesn’t.
A third activity based on diagrams a bit like the cover image. Using shapes made from different arrangements of identical rectangles, pupils work out the perimeters of increasingly elaborate shapes, some of which can’t be done. Questions have been designed so that only slight alterations have been made from one diagram to the next, but the resulting perimeter calculations are varied, interesting and sometimes surprising (IMO!). Has the potential to be extended by pupils creating their own shapes and trying to work out when it is possible to calculate the perimeter.
Plenary:
A closer look at the impossible questions, using a couple of different methods.
Printable worksheets and answers included, where appropriate.

Main:
Examples and questions to dscuss, on visualising distances and angles within cuboids and triangular prisms, and understanding the wording of exam questions on this topic.
Examples and quick questions for pupils to try, on finding the angle of a space diagonal.
A worksheet, in three sections (I print this, including the starter, two per page, two sided so that you have a single page handout), with a progression in difficulty. Starts with finding the space diagonal of a cuboid, where the triangle pupils will need to use has been drawn already. The second section looks at angles in a triangular prism, and pupils will need to draw the relevant triangles themselves. The third section has exam-style questions, where pupils will need to identify the correct angle by interpreting the wording of the question. (eg “find the angle between the diagonal AE and the plane ABCD”).
An extension task looking at the great pyramid of Giza.
Plenary:
A final question to add a bit more depth, looking at the most steep and least steep angles up a ramp.
Printable worksheets and worked answers included.

A complete lesson on the theorem that angles in the same segment are equal. I always teach the theorem that the angle at the centre is twice the angle at the circumference first (see my other resources for a lesson on that theorem), as it can be used to easily prove the same segment theorem.
Activities included:
Starter:
Some basic questions on the theorems that the angle at the centre is twice the angle at the circumference, and that the angle in a semi-circle is 90 degrees, to check pupils remember them.
Main:
Slides to show what a chord, major segment and minor segment are, and to show what it means to say that two angles are in the same segment. This is followed up by instructions for pupils to construct the usual diagram for this theorem, to further consolidate their understanding of the terminology and get them to investigate what happens to the angle.
A ‘no words’ proof of the theorem, using the theorem that the angle at the centre is twice the angle at the circumference.
Missing angle examples of the theorem, that could be used as questions for pupils to try. These include more interesting variations that incorporate other angle rules.
A set of similar questions with a progression in difficulty, for pupils to consolidate.
Two extension questions.
Plenary:

A complete lesson on the alternate segment theorem.
Assumes pupils can already use the theorems that:
The angle at the centre is twice the angle at the circumference
The angle in a semicircle is 90 degrees
Angles in the same same segment are equal
.Opposite angles in a cyclic quadrilateral sum to 180 degrees
A tangent is perpendicular to a radius
so that more varied questions can be asked. Please see my other resources for lessons on these theorems.
Activities included:
Starter:
Some basic questions to check pupils know what the word subtend means.
Main:
Animated slides to define what an alternate segment is.
An example where the angle in the alternate segment is found without reference to the theorem (see cover image), followed by three similar questions for pupils to try. I’ve done this because if pupils can follow these steps, they can prove the theorem.
However this element of the lesson could be bypassed or used later, depending on the class.
Multiple choice questions where pupils simply have to identify which angles match as a result of the theorem. In my experience, they always struggle to identify the correct angle, so these questions really help.
Seven examples of finding missing angles using the theorem (plus a second theorem for most of them).
A set of eight similar problems for pupils to consolidate.
An extension with two variations -an angle chase of sorts.
Plenary:
An animation of the proof without words, the intention being that pupils try to describe the steps.

A complete lesson on the theorem that the angle in a semicircle is 90 degrees. I always teach the theorem that the angle at the centre is twice the angle at the circumference first (see my other resources for a lesson on that theorem), as it can be used to easily prove the semicircle theorem.
Activities included:
Starter:
Some basic questions on the theorem that the angle at the centre is twice the angle at the circumference, to check pupils remember it.
Main:
Examples and non-examples of the semicircle theorem, that could be used as questions for pupils to try. These include more interesting variations like using Pythagoras’ theorem or incorporating other angle rules.
A set of questions with a progression in difficulty. These deliberately include a few questions that can’t be done, to focus pupils’ attention on the key features of diagrams.
An extension task prompt for pupils to create their own questions using the two theorems already encountered.
Plenary:
Three discussion questions to promote deeper thinking, the first looking at alternative methods for one of the questions from the worksheet, the next considering whether a given line is a diameter, the third considering whether given diagrams show an acute, 90 degree or obtuse angle.
Printable worksheets and answers included.

A complete lesson on the theorem that opposite angles in a cyclic quadrilateral sum to 180 degrees. Assumes that pupils have already met the theorems that the angle at the centre is twice the angle at the circumference, the angle in a semicircle is 90, and angles in the same segment are equal. See my other resources for lessons on these theorems.
Activities included:
Starter:
Some basics recap questions on the theorems already covered.
Main:
An animation to define a cyclic quadrilateral, followed by a quick question for pupils, where they decide whether or not diagrams contain cyclic quadrilaterals.
