In this curriculum unit, students reconsider the events leading to U.S. entry into World War I through the lens of archival documents.

This lesson unit is intended to help you assess how well students are able to: recognize and use common 2D representations of 3D objects and identify and use the appropriate formula for finding the circumference of a circle.

In this lesson, students will examine a preselected set of newspaper articles drawn from the "Chronicling America" website. They will determine the right each article illustrates and the responsibility that comes with that right.

In this lesson, students compare and contrast two photographs of women. In doing so, they evaluate how a photo creates a mood and how photos can encourage or challenge stereotypes. This activity is part of the Using Photographs to Teach Social Justice series.

This lesson unit is intended to help teachers assess how well students are able to understand and use directed numbers in context. It is intended to help identify and aid students who have difficulties in ordering, comparing, adding, and subtracting positive and negative integers. Particular attention is paid to the use of negative numbers on number lines to explore the structures: starting temperature + change in temperature = final temperature final temperature Đ change in temperature = starting temperature final temperature Đ starting temperature = change in temperature.

In Lesson 1, students focus on the first stave of the novel as they identify the meanings of words and phrases that may be unfamiliar to them. This activity facilitates close examination of and immersion in the text and leads to an understanding of Scrooge before his ghostly experiences. In Lesson 2, students examine Scrooge’s experiences with the Ghosts of Christmas Past, Present, and Future and discover how Dickens used both direct and indirect characterization to create a protagonist who is more than just a stereotype. In Lesson 3, students focus on stave 5 as they identify and articulate themes that permeate the story.

Expose middle school students to a first taste of Shakespeare from the angle of the ghost story and launch into the subject of verbs. In this lesson, they learn how Shakespeare uses verbs to move the action of the play. Students then distinguish generic verbs from vivid verbs by working with selected lines in Hamlet's Ghost scene. Finally they test their knowledge of verbs through a crossword interactive puzzle.

These activities will help students make connections between the foods they eat every day and the harsh experiences of the undocumented female workers who play an essential role in bringing that food to them.

This lesson helps students "hear" some of the diverse colonial voices that, in the course of time and under the pressure of novel ideas and events, contributed to the American Revolution. Students analyze a variety of primary documents illustrating the diversity of religious, political, social, and economic motives behind competing perspectives on questions of independence and rebellion.

This lesson is the third in a series called Expanding Voting Rights. The overall goal of the series is for students to explore the complicated history of voting rights in this country. Two characteristics of that history stand out: First, in fits and starts, more and more Americans have gained the right to vote; and second, the federal government has played an increasing role over time in securing these rights.

Students research archival material to examine nineteenth and early twentieth century arguments for and against women's suffrage.

Clues to Walt Whitman's effort to create a new and distinctly American form of verse may be found in his Notebooks, now available online from the American Memory Collection.  In an entry to be examined in this lesson, Whitman indicated that he wanted his poetry to explore important ideas of a universal scope (as in the European tradition), but in authentic American situations and settings using specific details with direct appeal to the senses.

In this lesson, students explore the historical context of  Walt Whitman's concept of "democratic poetry" by reading  his poetry and prose and by examining daguerreotypes taken circa 1850.  Next, students will compare the poetic concepts and techniques behind Whitman's "I Hear America Singing" and Langston Hughes' "Let America Be America Again," and have an opportunity to apply similar concepts and techniques in creating a poem from their own experience.

It happens in almost every classroom community: Someone has something someone else wants. Someone has the hottest new video game, sneakers or action figure; someone else feels jealous and expresses these feelings in unproductive ways. Issues of class and materialism underlie these interactions, and children often lack ways to talk productively and openly about what is really going on.

The lessons that follow will start a conversation about material consumption. We will explore why we want the things we want, how it feels not to have everything we want, and how to appreciate non-material possessions that can make us rich in deeper ways. In the upper elementary grades, children will also be encouraged to think critically about media messages and will have an opportunity to engage in a social action project aimed at minimizing materialism and entitlement.

In this lesson, students explore the First Industrial Revolution in early nineteenth-century America. By reading and comparing first-hand accounts of the lives of workers before the Civil War, students prepare for a series of guided role-playing activities designed to help them make an informed judgment as to whether the changes that took place in manufacturing and distribution during this period are best described as a 'revolution' or as a steady evolution over time.

In this lesson, students explore the First Industrial Revolution in early nineteenth-century America. Through simulation activities and the examination of primary historical materials, students learn how changes in the workplace and less expensive goods led to the transformation of American life.

Students weigh the choices Washington faced in the nation's first Constitutional crisis by following events through his private diary.
