    Bounds of error: introduction

    Lesson presentations and activities

    • This is a complete lesson I used for an OFSTED inspection. Did not get observed with this lesson though. Let me know what you think. There is a second lesson after this involving calculation of upper and lower bounds

    • This is a matching activity on bounds (it does what it says on the tin?), including the potential error in calculations. Ideal for a starter or plenary and should hopefully generate discussion and enable students to demonstrate understanding.

    • The powerpoint starts with recapping the different inequality signs.
      There is then a game of 'if this is the answer what is the question' linking to the fact that finding bounds is like being given the answer to a rounding question and working backwards to find what numbers could have been in the question.
      Then to explain how we find the upper and lower bounds I have used a number line with colour coding on what numbers would round, I have then zoomed in on the last section a few times to show we get closer and closer to the upper bound.
      Next is a slide to show the upper and lower bounds written just as bounds and also as an error interval.
      Finally there are 5 questions each on finding the error interval of a numbers rounded to 10, 100, 1dp and 2dp.

      A very good resource. Well set out and a real bonus to go from whole numbers to decimal places

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

    • Using calculator display screens with digits removed, pupils are asked to use inequalities to show the maximum errors in truncating the numbers

      Excellent - thank you!

    • The worksheet starts by asking pupils to state the upper and lower bounds of values, rounded to differing degrees of accuracy. The differentiated sections work through tougher numbers, to inequality notation and on to a challenge of 'working backwards' from the inequality notation.
