This lesson looks at algebra and the process of finding the 'nth term' and recognizing number sequences. Detailed and visual explanations are given to help learners understand how this is calculated in a step-by-step way. The PowerPoint includes lots of questions and answers to allow students to practise their skills. This also reduces the need for printing. This resource will prove useful in any math lesson. Learning aims are also included so students can measure their level of understanding and success in class. A lesson I have enjoyed teaching myself!
