Iterations

The resource consists of a lesson presentation and a worksheet. The lesson presentation includes a starter and worked solutions to the questions on the worksheet.

The starter involves proving that a root lies between two values of x. There is an optional exercise if students require more practice at this. Iteration is then explained and an example given. The worksheet asks students to do three iterations to find solutions to specified degrees of accuracy. Extension involves two iterations that don’t work and identifying the re-arranged equations that are equivalent to the equation to solve.
