I wanted my trig students to memorize the unit circle and the special angle trig values so what better way than to do something creative? I present to you my first ever unit circle art!

This is the rubric I used to grade them and they later taped into their INB.

P.S. This is not the thing that helped them memorize anything. But it was fun. Possibly more fun for me.

Looks fun! I'm curious as to what did help them memorize the Unit Circle? Friends of mine are teaching the Unit Circle and were brainstorming ideas on how to help the students remember.

ReplyDeleteLetting them figure out their own patterns seemed to help the most as well as practicing filling out an empty unit circle over and over. That helped them see what they were forgetting. Then as a class students shared the different things that helped them see a pattern.

ReplyDeleteStudents figured out their own patterns to help them rember. My favorite was what they noticed for radians. In the second quadrant, it is one 'slice' away from halfway/180/pi. So the fractions are all one away from the denominator 2/3, 3/4, 5/6. In the third quadrant they are one over so 4/3, 5/4, 7/6. And in the fourth quadrant they are almost double/360/2pi so double the denominator minus one: 5/3, 7/4, and 11/6. Hooray for patterns!

And the hand trick also helped them learn the ordered pairs.

Love this idea! I def want to use this in my Math III class this year. Is there anyway I can get the word doc file for the rubric? Did you have instructions that you handed the kids? OR did you just verbally explain to them that they were creating a unit circle out of materials?

DeleteIf that doesn't work, leave your e-mail and I will send it to you.

The only instructions they received were that it could not be made out of paper and it should be labeled with everything we had labeled our notes with.

I just want to say thank you for all the great ideas! I have been teaching trig for two years and am always trying to improve it. I will be using many of your great ideas especially this one. Also thank you for posting the resources.

ReplyDeleteThanks! I'm glad you found something useful. :)
