Trig Mini Poster Project
This is my origin yr didactics trig, then I'm figuring out a lot of things every bit I go. There is no textbook. No pacing guide. Just my ain experiences amongst taking trig inwards high schoolhouse to guide me. This is both exciting. And scary.
My memories of high schoolhouse trigonometry involve lots of graphing on the calculator. I didn't desire to possess got this approach. My kids already look to rely to much on the computing machine to practice their thinking for them. And, I experience similar i of the areas I failed these kids inwards Algebra two was transforming functions. When they run into a trig function, I desire them to actually run into together with intend most what is going on amongst the graph, non only type an equation inwards their computing machine together with sketch the result.
So, long even out short, my kids didn't actually freak out when I asked them to graph trig functions past times hand. In fact, they intend it's a completely normal affair to do. Yay :) Eventually, I had to tumble the beans together with acknowledge to them that I uncertainty their college professors volition e'er inquire them to graph a translated tangent graph past times hand. "But why not? It's then easy!"
One affair I've done this yr is inquire my students to practice mini-posters that summarize how to graph diverse trig functions past times hand. Some of my kids did a much improve chore at this than others, but I intend they all learned from this process. Instead of giving them each an equation to graph, I had them brand their ain equation. (However - they can't job the equations from their notes or their neighbor's equations!) Because my kids are smart/lazy/, they started thinking most what a,b,c,d values would brand their functions slowly to graph. A lot of them realized that if they changed the b value on their sine or cosine graph to pi, they could grade their x axis inwards damage of integers instead of inwards damage of pi. And, the best affair would move when my kids accidentally made mistakes amongst their graphing. Normally, mistakes wouldn't brand me that happy. But, then many of my students would figure out how to modify their equation to delineate of piece of work organization human relationship for the "mistake" instead of re-graphing the entire function. Then, it wasn't a fault anymore. :)
I snapped approximately pictures of the posters made past times my students. Some of these possess got errors. So, delight don't possess got them for gospel!
Notes to myself for adjacent fourth dimension I learn trig:
* Take improve notes over how to identify/label the period/amplitude of a graph
* Have students practice everything but the finally graph inwards pencil. Graph the finally graph (after translations) inwards color.
* Give the mini-poster projection every bit an assignment BEFORE the quiz instead of afterward it. Lots of awesome learning happened inwards the process. :)
