Graduated Page Book with Radian Circle

My collegiate son will soon be entering the Trig section of his Physics class. While that may sound like lots of fun, I know that he feel less than delighted when he encounters problems that require him to, say,  find the cosine of 135 degrees. Of course he can look at a handy chart like this one below:

Radian Circle

Radian Circle/ Unit Circle….memorize this….

I have actually been wanting to play around with the info on the radian circle, to see if I could simplify the look of it, to make it seem less scary.  Separating into four pages makes the patterns of the coordinates more obvious. Putting these separated sections into a graduated-page book  translates this idea  into an easily referenced tool.

This book structure has the novelty factor of having its pages staggered, which invites labeling the edges with the information that is located on the page. I’ve often used this structure with classes, especially when I am going for creating a book within a book, like in the weather book below.

Here, using the different layers of the book to generally reflect the different altitudes of different clouds helps to make these nebulous concepts more tangible.

On each page of this sample book drawings and information accompanied the label on the edge of the book.

A first grade teacher that I know, Mrs. Kavney, used this structure to create a book about ocean fish that live at different depths in the ocean. Since the drawing area on the pages gets larger one goes further into the book, and since ocean creatures tend to get larger in deeper ocean depths, I thought it was a fitting use of this structure.

A third class that I worked with made a book about Brazil that included a graduated page book about the rainforest. I had envisioned using the layers to describe layers of the rainforest, but the teacher wanted to use the page heading more like chapters. The students seemed to be comfortable with the size and the format, and made really lovely little books.

There’s many ways to do variations of this structure. Over the next few days I hope to be able to put together a tutorial about how to make this structure…which is something I have been wanting to do for quite some time.   (Addendum: Graduated-Pages Tutorial is now posted!)

At the moment, though, I am basking in the glory of having given my son something that he called “AWESOME!”

  1. I’m so happy to have run across this post. I can’t wait to make some of these for my students/children. This will definitely help with the trigonometry and I’m going to do one for geometry too I think.

    –Isn’t it nice when our children say things your son did? You are helping him on his way to achieving academic success, and I think that is AWESOME!!!

    • I would love to see images of what your students come up with. The cool thing about doing the radian circle this way is that the patterns emerge so clearly, and then memorizing it actually seems possible. I am curious as to what age students you are teaching…

  2. I am currently homeschooling 3 at the ages of 6, 14, and 16. They are all artistic in their own way. While I have made books for them I am hoping to get them more involved in the book making part of the process this time around.
