I use to just tell the students to convert the angle to degrees, but that was avoiding the issue. <br /><br />I have found that if the students could move/act out the angles, they will remember their size. So, I take the students down to the gym to the wrestling mats=pre-made circles and plenty of space. Using masking/painter's tape, I make a line from the center of the circles to an edge to mark the positive x-axis. Using a bunch of cards, the students take turns walking around the circle "graphing" the angles in standard position. Teammates check the work--I made a graphing calculator program to draw the angle on the screen--and the cards are left on the floor. After typical pi radians are graphed, I give decimals, whole numbers, etc. After a while, I ask the small groups of students about any patterns they see: themes in denominators, positive/negatives, etc.<br /><br />PS. I did this once with dry-erase markers on tiled floor...doesn't really erase!Brad G.https://www.blogger.com/profile/13914566582344815994noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-21850364856473727682013-09-30T15:14:41.963-05:002013-09-30T15:14:41.963-05:00I really love how you made the idea of radians a c...I really love how you made the idea of radians a concrete idea. Normally it is just a teacher saying "this is what radians are, memorize it." The example you provided actually forced them to LEARN the concept, not just have them memorize it.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10220498.post-52110032751398557292013-09-30T10:34:46.435-05:002013-09-30T10:34:46.435-05:00I like the organization you have with the chart an...I like the organization you have with the chart and how students are able to see connections. When I was in school this was thrown at us to memorize, so in the end I wasn't really learning anything. I am currently a student studying to be a teacher with a concentraton in math. I like how at the end you mentioned allowing the kids to discuss strategies, and I believe that to be super important in kids learning. Thanks for sharing your strategy on radians.rcherryhttps://www.blogger.com/profile/17762475576575057956noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-8016466260463856742013-09-22T11:08:09.573-05:002013-09-22T11:08:09.573-05:00Thanks!

I love bringing it back. I also love the organization of the chart!TwistedAlgebrahttps://www.blogger.com/profile/13144152813653921471noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-64942644045993981832013-09-19T20:11:33.731-05:002013-09-19T20:11:33.731-05:00Sweet!
