Today I attempted to use a mind map with my Algebra 2 class. We went through the notes. The students worked through the assessment. We discussed the assessment to fix misconceptions. I gave them one more assessment question to help distinguish a function and non-function. Then... well... the thing I was so excited about last night.. the mind map of functions.
"Draw a circle in the middle of the paper. Write functions in it. Then draw four squares. The upper left is your definition of a function. The lower left is where you write some examples. The lower right is where you write non-examples. And the upper right...." Well, crap. Ever draw a blank? Quick. Think. Think. Think more quickly. Grab my phone and attempt to find the picture on pinterest? Where did I put my original? Think. Think. Oh no, three seconds has gone by. Say something. "Okay, and in the upper right corner... What does a function look like? Take two minutes and fill this out silently. Then we will share within our groups. Then I'm going to collect this before you leave." ... I hang my head for those two minutes. I blew it. I tried to salvage it. I had missed the facts/characteristics in the upper right corner. Que sera, sera.
I wasn't really expecting these to be stellar since I couldn't remember the first quadrant piece. But I got some awesome feedback none the less. I saw which kids really understood it, which kids just copied/regurgitated the notes right back at me, and which kids still had some misconceptions. I was able to give feedback directly on it. In short, I will do this activity again. But next time, I will have the correct information in front of me! And next time, I will stress the fact it was supposed to be in YOUR OWN WORDS.
Now, to have some sort of activity for the three different forms of graphing a line...
