If you haven't heard of Zoom In! (http://zoomin.edc.org/), then you are missing out! This website is a wonderful FREE resource to integrate literacy, reading and writing, into your social studies content, having students work at their own pace.
Zoom In! offers lessons for every period of American History. Each lesson takes students through context to learn about the event and then primary sources to argue an essential question. Students are taking notes throughout the lesson while close reading sources. The lesson ends with an assessment, usually an essay, in which students cite evidence from the documents and compose an essay in a structured manner. You can even differentiate how must support each student receives, and you can give formative feedback along the way!
I have created an instruction sheet to give to first-time students using Zoom In! It guides them through the process of signing up and then navigating a lesson. Mine is based off of Zoom In!'s Boston Massacre lesson, but it is easily customizable to whatever lesson you start with. Included is even criteria for an alternative summative assessments student may complete instead of the essay, allowing for personalization.
