About This Lesson
A Tarsia activity on difficult quadratics. 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 an excellent tarsia on quadratics, students could either be asked to expand the quadratics in brackets, or to factorise the quadratics not in brackets. The quadratics range in difficulty from simple cases to questions where a = 2 and a = 4, there are also questions using the difference of two squares. This would make an excellent activity at any stage of the lesson and would also allow you to listen to student discussion on this topic which can be so valuable. Thank you for sharing.
