Covers all aspects of the GCSE specification on iteration (and term-to-term sequences). Includes an exercise and an explanation of why the iterative method works.
A PPT that goes through how to answer iteration questions for Year 10/11 students on the new GCSE. Finishes with some very tough questions, including a wordier problem. Also includes a bonus Throwback Thursday starter! Worksheet attached is one I found on the internet, so can't claim credit for that!
A powerpoint and worksheet with practice then exam questions to revise iteration. Goes through the three main parts of a standard iteration question first.
8 Questions with graphs to iterate and find estimates for solutions. Answers provided.
4 iteration questions from Edexcel specimen assessment materials. Mark scheme attached.
Worksheet containing five example questions on iteration. Answers included.
It used to be quite easy to come up with examples to teach/practise trial and improvement, but using iteration is a very different beast and needs some carefully chosen and prepared questions. This worksheet contains a brief introduction/reminder about iterative formulae and their use in sequences, then has one example of using iteration to find a root of an equation, to work through as a class. The following exercise has 7 questions for students to attempt on their own. Answers are included.
I created this card sort for my middle set year 10. The students cut out the cards and rearrange them to create a complete set of worked solutions. I found these helpful for the students who were not very strong with changing the subject of a formula. Created in word so you can change to make the questions easier or more challenging depending on your class. Suitable for new curriculum. 02/03/16- small error on final line of Q1 now corrected.
In this lesson, students learn what iteration is and see an example of how it was used to calculate square roots of non-square numbers. There is an explanation of the notation involved and students get to try the process out for themselves. Could be used as an introduction to the topic.

Students show a solution lies between two numbers and rearrange the formula to a given arrangement, then use this to find a solution. (answers included) The extension task has one formula rearranged in three different ways. A further extension could be to find other ways of rearranging the other four to find the other solutions.
Lesson on iteration, for the new GCSE, made for edexcel board , iterations worksheet included
4 lessons taking students through processes required to understand the Mandelbrot set and fractals. Students should already know how to simplify surds and expand a double bracket. They will learn about imaginary and complex numbers, Iteration and Argand diagrams. The spreadsheet can be used to help map out points that satisfy the Mandelbrot set. Aimed at very high ability KS4 students. If you like this resource then please check out my other stuff on here! :) (and thanks to danwalker on TES for the idea for the spreadsheet!)

Having already taught iteration. I created this SMART notebook and worksheet for my higher tier year 11 students to revise this topic.
A roundup resource to finish a series of lessons on Growth, Decay and Iteration (specifically the AQA syllabus). Lots on compound interest and exponential decay, with questions on iteration notation included.
An introductory lesson with differentiated worksheet introducing the concept of iteration to lower ability groups who can then progress to making their own iteration machines for the following lesson by re-arranging. If uploaded please comment (positive or negative).
Answers included too.
