About This Lesson
A Tarsia activity on Factors and Multiples. These type of activities can be used to consolidate understanding of a given topic, and foster positive group work and co-operative learning. For more ideas on how to use these types of activities (including twists!) and to download the latest version of the wonderful free software to open this resource (and create your own), just click on the web-link. If you have any comments, or spot any (non deliberate!) mistakes, please share them below. Many thanks to all the teachers who have helped me assemble these Tarsias over the years.
This is a really nice activity on factors, HCF, LCM and prime factor decomposition. This would be an ideal activity at the end of the topic since it requires students to understand quite a lot. Some of the questions are simple but some ask students to calculate HCF and LCM from numbers written as products of their prime factors. Although you could very quickly adapt this to suit your class, thank you for sharing.
