I wish I didn't run out of time in class today. It was going so well.
This is an Accelerated Algebra 2 class. We have been learning right triangle trig with law of sines, cosines, bearings, and the unit circle. We did a station review today to prepare for a quiz on Monday. I loved making it with help from all over twitter, blogs, and #mtbos. (Sometimes the hardest part about blogging is remembering who to give credit to. I hope I get it right.)
Thanks for Julie @jreulbach for the reminder about using stations in the first place.
Station 1: Trig Word Problems with QR code answers - Julia @jfinneyfrock told us on twitter that Snapchat is a QR code reader. Cool!
Station 2: Radian clothesline. I used my clothesline in Dec for logs and exponents, pulled it out today to put radians in order from 0 to 2pi. Clothesline idea: Andrew writes about Clotheslines here with an idea from Chris Shore
Station 3: Angle vocabulary - Vertical Non-Permanent Whiteboards (idea from @AlexOverwijk and blog - (mine were permanent) get them up to the board drawing angles, reference angles, coterminal angles
Station 4: Unit Circle practice also VNPS at the board
Station 5: Law of Sines and Cosines applications with more QR codes
Station 6: Trig Match Up - a sorting activity from Shireen over at Math Teacher Mambo
I think the kids liked it. They were moving around and asking questions. Here are some pictures:

A quick blog post. I taught bearings in Accelerated Algebra 2. They did bearings last year in Geometry and didn't really like it from the moans and groans when I announced it yesterday. We are doing a unit on trig with Law of Sines and Cosines and bearings as well. We do one day of bearings. I wanted to see what they remembered as well as make them see bearings as necessary. So, I opened with this: Edited to give credit to Dan Meyer for blog post.
