It is great that as teachers we can use technology to find lesson plans that contribute or assist to our own lesson plans. This site has an entire unit on The Great Depression and New Deal that involves multiple research based strategies such as cooperative learning and non linguistic representation. I actually used one of the lessons during my practicum and the kids loved it!
I found this website that offers free graphic organizers for teachers to help them provide a varied, exciting curriculum. These GOs can be used in all subjects. I think it is important to include organizers such as these in our curriculum to especially assist in students with special needs and culturally/linguistically diverse individuals. Enjoy!!
