An ACTIVITY on Angles in Parallel Lines fluency and extension. This is a scaffolded, differentiated, engaging and accountable activity that promotes discussion between students while being fun at the same time. The idea for this activity is borrowed from Rich Walter in this TES video I saw. If you’d like to get an idea of how this works in the class, watching the video would be a good idea. It takes me 10 minutes to prepare for this activity using the resources in this download though it may take you a little longer the first time. Requires: Post-It Notes (Sticky Notes) A (manual feed) printer. Don’t use the large school photocopier. ‎ Download Contents: Template to help print Post-It notes Parallel lines questions (to print onto Post-It notes) Image of instructions given to students ‎ Notes from experience: Post-It notes actually have a proper method to peel them off. Using this method lets them sit nicely on the whiteboard. If the notes lose their stickyness quickly, place a table or two under the whiteboard to return them to instead. Keep an eye on the names students are writing. Keep an eye out for common misconceptions where everyone has written the same incorrect answer, particularly with the challenge and super challenge questions.
