    Graphs of circles

    Lesson presentations and activities

    • I used this for my year top set 10 group who needed to be able to recognise equations of circles, identify co-ordinates on a circle, and the radius of the circle. It was an investigation I found on tes (thank you to misslv) which I adapted! This is a discovery task and found it worked brilliantly for my group by the end of the lesson all were able to identify equations of circles, and give equations with a given radius. Some could even give different equations with the same radius but different centre, and recognised what the centre would be. There are follow up questions to deepen and check understanding. The only thing that is not here is the giant A3 axes that I created and photocopied of thr groups, I just used A3 paper and drew some -10 to 10 axes (one for each set of circle equations).

      If you download please leave me a review! Thanks.

    • A lesson on the equation of a circle centred at (0,0).
      From initial discovery to solving, graphically, simultaneous equations with a circle and a straight line.
      Included are:
      Starter - Tacking misconceptions around substitution with negatives and squared terms
      Exploration - testing out coordinates and discovering the link with Pythagoras' Theorem
      Examples - models for pupils from basic drawing to finding solutions to simultaneous equations
      Worksheet - solutions provided with problem solving elements and key intervention points addressed
      Extension plenary/ summary - links to inequality regions, area and solution in terms of pi
      Homework - pupils to master understanding by demonstrating a "no solutions case"

      my students appreciated the equations being worked out step by step in front of them, and the simplicity of the diagrams - said they understood it easily from your powerpoints. thank you!!

    • Starts easy and gets harder but essentially does what it says on the tin. A challenge for GCSE, a starter for A Level. There may be more hence the "1".

      Thank you for publishing your resource. It has been selected to be featured in a new secondary maths collection.

      Love these! Thanks

    • Updated 4/3/2017 - typo errors corrected on page 1 of solutions, part b. Updated 8/3/2017 - extra exercise added to question 1) b); solution on page 1a.

      This worksheet has two problems involving circles centred on the origin. The first problem requires the equation of a tangent line to be deduced. The second problem requires a set of simultaneous equations to be set up to find the x and y co-ordinates where the line cuts the circle. When combined these form a quadratic equation. The equation will not factorise, so completing the square method or the Quadratic Formula must be used to solve it. DOCX and PDF worksheets supplied along with 3-page written solution in JPG format.
