I always get inspired when I go to a teaching conference. If you've never been to a Good Teaching Conference in your state, I would suggest you try to go at least once. They invite presenters who are very knowledgeable. I've always left with new ideas and things I want to try with my own class.
I learned about a few free resources that I thought others who were not aware of may benefit from. Did you know if you go to http://www.pbslearningmedia.org/ then click on the subject there are videos for students and most of them have extension activities. They also tell you which standards they are aligned to. A great resource to be aware of.
The next website is http://betterlesson.com/. This site has lessons that great teachers have created.
Then there was https://www.mydigitalchalkboard.org/. Another site where lessons are posted. You do have to join the community to have access to their lessons. You can choose your lesson and topic.
One of the sessions I went to was how to put Engineering into STEM in the primary grades. A resource she spoke about was http://eie.org/. This is a resource for purchasing lessons. She did say if you were interested in the binder, you could purchase just that, then go to the 99 Cents Store to purchase all of the supplies, rather than purchasing the whole kit. She says she's bought 5 of them and the first time she bought the kit. The next 4 she only purchased the binder and said she was able to find 99% of the items used in the engineering binder at the 99 Cents Store.
I thought I'd share these resources with you as most of them are free. Thanks for visiting.
