A nice person commented from my last post and showed me some applets she'd made for Geogebra (thank you Lsquared). This must have planted a seed in my mind, because today I was tinkering around with how to start up my trigonometry unit. I went to the Geogebra site. I clicked "download". Then I clicked "Applet Start". I figured my kids don't have downloading capabilities on the school computers, so this would be fine.
I tinkered around with things and came up with this activity. I'm going to make a worksheet that goes with it to guide them through a self teaching, first day of trig, what is sine/cosine/tangent activity. I think some of the questions may even be of the effect of, "set your triangles, set up your calculator just so, press cos ____ (degree shown), compare it to ratio."
I would love feedback on this "non applet". Effective? Hard to manage? Fine?
Note: I tested out opening the file on another computer. It "failed" with Firefox, but worked fine with Explorer. I DID have to change the window size to 200% or something like that. But there is a way to show WHOLE picture.
Anyway! Off to write the worksheet. I'll share. Okay, really off to dinner then Lindy Hop, then Marfa, THEN to write the worksheet.
