I will be teaching 4 different classes. Two will be an entire ELA block (90 minutes), one will be math (60 minutes) and the other will be S.S. (40 minutes). I know it sounds extreme but let's just say that I need to prove myself to the right people. I am desperate for as much help as possible because two of the lessons will take place at the end of next week. ELA can be anything related to typical 4th grade reading and writing. S.S. should be related to Immigration/Industrialization and to be honest with you, I have no idea what math should be because I haven't taught it to that grade before. I believe they are doing something with Angles right now. I was told that these could all be "demo" type lessons so I can do what I like. As you can see though, I have a lot of time to fill up, especially for ELA. The only guidance I received was to "keep it simple" and set very clear objectives, have ongoing assessment and closure to the lesson. Any ideas you can offer would be greatly appreciated!
