So math teachers I need your opinions... What are the chances that I could teach a class strictly on trig (sin, cos, tan, ect) for 12 weeks? We are on trimesters and I get to design my own classes, and wondering if that is an option? The kids I teach are a little bit lower than normal, and range anywhere from 9th grade to senior level math abilities. What do you think?

I've seen a year long trig class, so I think that this would be entirely possible. Imagine the depth you could go into with real world applications of trig!

That's what I was thinking... Do you happen to have a copy of a calendar or anything? I've taught basic trig, but not in depth stuff...

Completely possible I feel the same way. My trig course was 18 weeks. I would include lots of the application of the trigonometric functions. That would also include some of the construction applications that may lead to some larger units or projects.

There's an awful lot of trig you could include: - Basic SOHCAHTOA stuff - verbals, angle of elevation and angle of depression - Right triangle problems where you have to find one side, say the hypotenuse of the large triangle, then use that side in a second adjacent triangle. - Reference angles, CAST, trig with angles greater than 90 degrees - Special angles: 30, 45, 60 degree values - The unit circle and 0, 90, 180, 270, 360 degree values - Law of Cosines - Law of Sines - Ambiguous Case - Solving triangles - forces - Reciprocal trig functions - Graphing trig functions - Proofs of trig identities Even Polar coordinates if you wanted to. It wouldn't be incredibly hard to fill up 12 weeks.

Not that it's pertinent, but it just occurred to me to ask: What are they learnng the other 2 trimesters?

It would be fun to teach a trimester course on graphing an assortment of functions-- withOUT a graphing calculator. Linear, Quadratic, Absolute Value, Square Root, Rational, Polynomial (LOVE those!), trig, conics, polar.... Or one on proofs: - logic - coordinate - geometric - trig - inductive reasoning-- I always LOVED those too!

Thanks Alice!! See, what they have learned the other two trimesters could be whatever. They aren't nessicarily the same kids that I have had all year. I teach at an alternative high school, so their classes change - but the ones that have been in the same two hours have been learning about geometry or graphing - so some exposure. Their abilities range anywhere from basic algebra to advanced algebra 2... so I need to make sure it can be differentiated for everyone.
