You have a great start on your lesson plans. I would suggest you think more about your second lesson plan. If students post their answers on Blogger, wouldn't students just copy other students' work.
Subject: Social Studies Activities
This lesson plan is an interactive social studies project. For third graders learning about the United States. They will be assigned into teams of two and each group will have assigned two states and have to research information about each state.
Internet for research
Subject: Reading and Writing Activity
After reading a short story, Fourth grade students will discuss the story through short written responses. They will also apply their computer skills and upload their responses on Blogger. They will engage in discussions with other students who have also read the short story. They will then have a better understanding of the material.
