Day 93: Parallel & perpendicular slopes January 28, 2014February 28, 2014 Lisa Bejarano 180 Days of Geometry 13-14 ISN, parallel lines, perpendicular, slope We had a 2 hour delay today, but students were able to complete this with very little talking from me!
day 34: Properties of parallel lines & transversals October 2, 2013February 6, 2014 Lisa Bejarano 180 Days of Geometry 13-14 angles, geogebra, Geometry, parallel lines It was frustrating for students to construct using geogebra, so this morning I made 2 parallel lines & a transversal & measured each angle. They got to move lines around and observe changes in angle measurements.
day 33: Geogebra frustration October 1, 2013February 6, 2014 Lisa Bejarano 180 Days of Geometry 13-14 geogebra, Geometry, parallel lines I think it is good that students were so frustrated about GGB, because they didn’t quit and they can work on this more tomorrow.
