Trigonometry Pile Up

This activity for your Trigonometry class comes from William Emeny.   You can go to his site by clicking here. 

The Unit Circle

This looks like a great activity and manipulative that your students can use for the unit circle.  I could not find the kit to make this though.  However I did find a Teachers Pay Teachers free download of a very similar thing.  Click here to see it.  I think just using the push pin like above to rotate the triangles is awesome.

Graph Paper and Grid Images

The name says it all.  My daughter is taking grade 10 math and she was in dire need of graph paper.  Rather than try and draw it on regular lined paper or run out and by a pad of graph paper this site has the different type of papers you will need.  If you are graphing parabolas, trig functions or just listing a table of values and the associated graph, it is all there.  This site will have graph paper that you could use for science experiments.   Click here to see the website.

Unraveling the Unit Circle Using Spaghetti

If you are teaching how to graph the sine and cosine function here is a nice and possible messy way of doing this for you students that they should find fun.   The video that is  posted on their website can be found by clicking here or looking below.

Photomath

From their website, "Photomath is a mobile application described as a "camera calculator", which utilizes a phone's camera to recognize mathematical patterns and to display the solution directly onscreen. It is available for free on Google Android and iOS"

I have utilized this app on my phone and it works well with typed questions and even on my hand written questions.  Not only will it show you a solution but will show you the steps used to get the solution algebraically and graphically.  This works from basic arithmetic through trigonometry and Calculus.  To see the webpage click here.  The downloads can be found for iOS by clicking here  and for Android by clicking here. 

sine, sine, every where sine

From the Science March in April 2017.  It might be something you can use when you start trig.

Trigonometric Functions using real world examples

Kathy Stevens from Calgary Alberta had her students involved in a series of labs that highlighted trigonometric functions.  If you are teaching a course that deals with drawing sinusoidal curves this might be a good watch.  Just click on the Watch on Vimeo button below.
