A professional growth plan is a personal goal so it would be hard to share mine and have it meaningful for you. Think about your own needs: What areas of math instruction do you feel a need to improve in? What new strategies would you like to try? Maybe you'd like to create math centers or use math problem solving notebooks? Maybe incorporate more math manipulatives in your lessons? Let us know and then maybe we can help with the wording....
I'd like to do the plan in writing. I'm always using journals a lot, but I need a plan of action to make the writing better. I need to know some ways to increase more interesting writing. I could use some strategies to do that.
I agree that professional development plans are so personalized that I don't think anyone can write it for you. You need to think about yourself as a teacher and devise your own ideas for what you need/want to improve.
Seeing someone elses can help with wording but it really won't have any meaning or be any help to you as a professional if it's not your own.
