A Tarsia activity on perpendicular lines. 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 dominoes activity on perpendicular lines, students must match up the perpendicular equations using their gradients. This would make an excellent activity at any stage of the lesson and would allow you to listen to student discussion which can be so valuable. This can be easily adapted to include some extension questions if you wanted. Thank you for sharing.
