Last week I wrote about my idea for an activity for investigating SSS. Helpful ideas were provided in the comments: using straws and string, Geogebra, and Polystrips to name a few. The year before we used the string and straws for this concept. It worked well.
Despite having something that was okay last year, I changed it. I shouldn’t have. Despite asking for your advice, I didn’t take it. I should have.
This year? Bleah. The strips were too hard to cut out and keep track of. They didn’t fit together well. The set that shouldn’t have formed a triangle? Some of them forced it by cutting off more of one side. The next day I tried to “fix” it. We talked about what should have happened. I don’t feel good about the way this lesson went. It was muddled. There was no a-ha moment.
So I’ve been wondering why I felt the need to do something differently this year. I don’t have a good answer. I think part of it is my fear of becoming the teacher who doesn’t change her lesson plans from year to year. I never want to say last year was good enough, I’ll just do that again. I want every lesson to be great. I know I’m not there yet. I don’t know if I’ll ever get there, but I’m trying.
How often do you repeat lessons from year to year? How often do you just tweak? How often do you scrap it all and start over?
I guess I’m just wondering when I’ll be satisfied with my lessons and my teaching. And if I ever should be.
