I adapted Jeff De Varona's Diamond Building lesson into a 3-act task, but instead of having act 3 be a reveal of the actual height, I had students calculate the height a second way to confirm their results. It took 2 short class periods (about 40 mins each) with my struggling students, but it may be able to be … Continue reading The Diamond Building

Being that it was "What we've been doing Wednesday" I changed the warm up after my first … Continue reading Day 102: Practice Right triangle trigonometry
