How Old Is That Tree?

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing its characteristics using a hand lens and play a game for lesson reinforcement.

I am actually not a teacher, yet. I am a college student on my way to becoming a high school math teacher. Lesson Planet has been a lifesaver on several occasions. I have used it for everything from learning how to word a lesson plan to using a lesson plan I found on the site to teach a mini-lesson. I use it quite a bit now so I know it will be invaluable in my teaching career. It is great as it is and so easy to navigate.
