Lesson Planet is an interesting site, that is for sure. We were given a free trial membership for our review. I happened to be researching some Unit Study ideas and have been looking for lesson plans, so since I was in the process of reviewing Lesson Planet, I started there.
Lesson Planet has an abundance of resources! There were 300+ lesson plans for the topic I was searching - even divided up into grade levels. I can see where this website would be an awesome benefit to teachers or to someone who struggled with finding and coming up with their own lessons.
*Disclaimer: This membership was given to me free in exchange for this review. For more reviews on Lesson Planet, please visit the Crew, linked above.
