Circles Starters:Pi Day: March 14th is Pi Day. The third month and the 14th day relates to 3.14 which is pi to three significant figures. How many figures of pi can you memorise? Refreshing Revision: It is called Refreshing Revision because every time you refresh the page you get different revision questions. Square Circle Kite: Write down the names of all the mathematical shapes you know.

Curriculum for Circles:Year 6Pupils should be taught to illustrate and name parts of circles, including radius, diameter and circumference and know that the diameter is twice the radius more... Years 7 to 9Pupils should be taught to calculate and solve problems involving: perimeters of 2D shapes (including circles), areas of circles and composite shapes more... Years 10 and 11Pupils should be taught to identify and apply circle definitions and properties, including: centre, radius, chord, diameter, circumference, tangent, arc, sector and segment more... Pupils should be taught to {apply and prove the standard circle theorems concerning angles, radii, tangents and chords, and use them to prove related results} more... Pupils should be taught to calculate arc lengths, angles and areas of sectors of circles more... Pupils should be taught to {recognise and use the equation of a circle with centre at the origin; find the equation of a tangent to a circle at a given point} more... Feedback:Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School: "What a brilliant website. We have just started to use the 'starteroftheday' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources online we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun." Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay: "An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!" Comment recorded on the 23 September 'Starter of the Day' page by Judy, Chatsmore CHS: "This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles." Comment recorded on the 8 May 'Starter of the Day' page by Mr Smith, West Sussex, UK: "I am an NQT and have only just discovered this website. I nearly wet my pants with joy. Comment recorded on the 17 November 'Starter of the Day' page by Amy Thay, Coventry: "Thank you so much for your wonderful site. I have so much material to use in class and inspire me to try something a little different more often. I am going to show my maths department your website and encourage them to use it too. How lovely that you have compiled such a great resource to help teachers and pupils. Comment recorded on the 28 September 'Starter of the Day' page by Malcolm P, Dorset: "A set of real life savers!! Comment recorded on the 7 December 'Starter of the Day' page by Cathryn Aldridge, Pells Primary: "I use Starter of the Day as a registration and warmup activity for my Year 6 class. The range of questioning provided is excellent as are some of the images. Comment recorded on the 12 July 'Starter of the Day' page by Miss J Key, Farlingaye High School, Suffolk: "Thanks very much for this one. We developed it into a whole lesson and I borrowed some hats from the drama department to add to the fun!" Comment recorded on the 10 April 'Starter of the Day' page by Mike Sendrove, Salt Grammar School, UK.: "A really useful set of resources  thanks. Is the collection available on CD? Are solutions available?" Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield: "I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information." 
Notes:This is all to do with pi and why it is such an important number. From finding the circumference and area of circles to problem solving and investigation. Circles Teacher Resources:Angle Theorem Kim's Game: A memory game to be projected to help the whole class revise the circle angle theorems. Circle Parts Kim's Game: A memory game to be projected to help the whole class revise the names for the parts of a circle. Circle Theorems: Diagrams of the circle theorems to be projected onto a white board as an effective visual aid. Circles Activities:Circle Equations: Recognise and use the equation of a circle with centre at the origin and the equation of a tangent to a circle. Circle Pairs: Find the matching pairs of circle diagrams and circle properties in this interactive online game. Circle Theorem Pairs: A pairs game based around ten theorems about the angles made with chords, radii and tangents of circles. Circle Theorems Exercise: Show that you understand and can apply the circle theorems with this self marking exercise. Circles: Practise using pi to calculate various circle measurements. There are six levels of difficulty. Proof of Circle Theorems: Arrange the stages of the proofs for the standard circle theorems in the correct order.
