This resource from the National Library of Virtual Manipulatives shows students how to rename fractions to have a common denominator and then add them. It is appealing because it visually engages the students by showing them what happens to a unit (a rectangle is used here) as the denominator increases or decreases. As the denominator increases or decreases, the partitions are shown accordingly, and the effect on the numerator is shown as well. This is a convenient, visual way to show students how to manipulate fractions for adding.

After gaining skill through analyzing a historic and contemporary speech as a class, students will select a famous speech from a list compiled from several resources and write an essay that identifies and explains the rhetorical strategies that the author deliberately chose while crafting the text to make an effective argument. Their analysis will consider questions such as: What makes the speech an argument?, How did the author's rhetoric evoke a response from the audience?, and Why are the words still venerated today?

This lesson asks students to explore the motivation behind characters' actions in To Kill a Mockingbird. Students first engage in a freewrite activity. They then do research and creative thinking to design a poster and plan a presentation representing a psychological profile for a selected character, while determining what specific factors (such as family, career, environment, and so forth) have the greatest influence on the characters' decision making throughout the novel. The groups present their findings to the class by assuming the persona of their character and explaining the psychological factors influencing their behavior in the novel.

What images symbolize hatred, peace, freedom, or confinement? What feelings do these images evoke in the viewer? What power do images have? These and many other questions provide the framework for students to use technology to explore symbolism in Elie Wiesel's Night. Students begin with a discussion of everyday symbols, such as street signs and hand gestures, to help them come up with their own definition for symbolism. Students then choose and analyze a passage from Night that uses darkness as a symbol, and then brainstorm how they might reinterpret their selected passage as an image. After learning about symbolism and discussing its use in the book, students create visual representations using an interactive tool. Students then express their response to the symbolism in the book by creating a photo montage using images from multiple websites about the Holocaust, text from survivor stories, articles about hate crimes, and Night.
