2 Iteration worksheets

2 worksheets on the topic of Iteration, with answers provided. Each worksheet is available as a pdf and a Word document, in case you want to make any changes.

In worksheet #1, all the answers are integers. I find this helps students understand the idea of a recursive formula, as they can perform all the calculations in their head.

Students are given a recursive formula and the value of x1, and must calculate the values of x2, x3 and x4. They then cross off their answers in the grid at the top of the page. Once they’ve finished the entire worksheet, there will be 6 numbers in the grid they haven’t crossed off. These 6 numbers add up to 100. This is a nice, quick way for you to check that your students have completed the task correctly!

The content on worksheet #2 is more challenging as students will need to know how to use the ANS button on their calculators in a recursive formula. This is just a simple practice worksheet - students write down the values of x2, x3, and x4 in the spaces and then move on to the next question.
