Upper School Academics


Grade 7 English

Seventh grade English is a skills-based course focusing on the development of students' writing, reading, critical thinking, and discussion skills. In addition to regular class discussions, which are often student-led using the Harkness method, class time is devoted to the exploration of English grammar, vocabulary, and public speaking.

Students examine and practice the structure of expository essay writing, learning to craft arguable, complex thesis statements and to support their ideas with evidence. Nightly writing assignments strengthen their ability to use writing as a tool for inquiry, and the practice of annotation prepares them for class discussions. Though the course emphasizes expository essays, students also craft poems, short works of fiction, and personal narratives.

Several projects challenge them to go beyond written analysis and express their ideas through visual or digital media, such as creating short original films based on Shakespeare’s A Midsummer Night’s Dream. In English 7, the study of individual texts is enriched by a year-long focus on the theme of how an individual interacts with his or her society. As part of English 7, all students participate in the public speaking program, in which they write, memorize, and present their own piece of narrative non-fiction.

Sample reading list:

  • Selected short stories (including Ray Bradbury, Kurt Vonnegut, Jack London)
  • The Outsiders, S.E. Hinton
  • The Giver, Lois Lowry
  • Selected poetry (including Sherman Alexie, Margaret Atwood, Emily Dickinson, Langston Hughes, Walt Whitman, William Butler Yeats)
  • A Midsummer Night’s Dream, William Shakespeare
  • Haroun and the Sea of Stories, Salman Rushdie
  • English Workshop: First Course, Rinehart and Winston Holt
  • Rules of the Game: Grammar Through Discovery (Book 1), Peter Guthrie, Mary Page, and Sloan Sable

Grade 8 English

Eighth grade English is a year for students to fine tune and expand on skills introduced in seventh grade, specifically expository and creative writing, discussion and oral presentation, critical reading, and the use of more advanced vocabulary and grammar. Class time is spent on student-centered learning, as teachers continue to promote and build critical thinking and intellectual risk-taking.

Through practice, students gain greater mastery in the Harkness method of class discussion, learning to effectively cite the text, express their ideas, build upon their classmates’ comments, and disagree in ways that contribute to the discussion. They explore key literary concepts such as theme, character, parallels, and motifs. In addition, through small group work and class presentations, students tackle more concrete literary devices such as subtext, irony, satire, and figurative language.

In English 8, the reading selections are designed to explore the American experience through literature, as well as to expose students to a wide range of genres. In this course, the practices of reading and writing reinforce one another as students explore these genres and rhetorical modes in their own creative and analytical work. For example, after reading Sandra Cisneros’sThe House on Mango Street, students are asked to write a series of personal, creative vignettes using Cisneros’s poetic writing style. While challenging students to expand the breadth and flexibility of their writing style, this process also helps them begin to develop their own academic voice. As part of English 8, all students also participate in the public speaking program, in which they write, memorize, and present their own piece of narrative non-fiction.

Sample reading list:

  • Selected short stories (including Borden Deal, Daniel Garza, Daniel Keyes, Edgar Allen Poe, James Thurben, James Ramsey Ullman)
  • Of Mice and Men, John Steinbeck
  • Inherit the Wind, Jerome Lawrence and Robert Lee
  • The House on Mango Street, Sandra Cisneros
  • Selected poetry (including Lucille Clifton, Billy Collins, Paul Lawrence Dunbar, Langston Hughes, Wilfred Owen, Carl Sandburg,)
  • Macbeth, William Shakespeare
  • To Kill A Mockingbird, Harper Lee
  • English Workshop: Second Course, Rinehart and Winston Holt
  • Rules of the Game: Grammar Through Discovery (Book 2), Peter Guthrie, Mary Page, and Sloan Sable
  • Vocabulary Workshop: Level C, Jerome Shostak

Grade 9 English

In ninth grade English, students master the ability to write well-structured essays and expand their ability to analyze subtle nuances of a text, preparing them for the increasingly independent work they will do throughout high school and college. As students delve into thematically important passages, symbolism, and imagery during class discussions, they are increasingly attentive to connections between different texts. They learn to identify allusions or references that illuminate meaning, such as the role of Emily Dickinson and Rupert Brooke’s war poetry inThe Catcher in the Rye. Tracing these connections is part of the course’s broader emphasis on critical thinking—going beyond superficial interpretations to consider the source, the author’s use of language and style, and the effect of these choices.

In their own writing, students continue to refine the mechanics of their prose style. Each paper assignment begins with a brainstorming session and transitions to a writing workshop, where students receive individualized guidance and practice “mini-lessons” such as effectively integrating quotes and using complex sentences to clearly express the relationship between ideas. This focus on process helps students establish the habits of success and builds confidence in their writing.

The selected readings provide a thematic cohesiveness to the year’s study. Students examine how different literary works portray the experience of coming of age, exploring how loss and the absence of authority are often catalysts for growing up. All students participate in the public speaking program, in which they write, memorize, and present their own piece of narrative non-fiction.

Sample reading list:

  • A Raisin in the Sun, Lorraine Hansberry
  • Selected short stories (including Mavis Gallant, Alice Munro, Alice Walker, Richard Wright)
  • The Catcher in the Rye, J.D. Salinger
  • The Great Gatsby, F. Scott Fitzgerald
  • Romeo and Juliet, William Shakespeare
  • Lord of the Flies, William Golding
  • Persepolis, Marjane Satrapi
  • Selected poetry (including Rupert Brooke, Emily Dickinson, T.S. Eliot, Alfred Lord Tennyson)


Grade 7 History

The seventh grade history curriculum focuses on the European Middle Ages, the Renaissance, and the Reformation, creating further links to several other cultural areas with whom the Europeans came into contact. Through the use of textbook and document-based primary and secondary source readings, interactive activities, historical fiction, videos, and research projects, the students develop a rich understanding of the varying cultures while becoming more adept at critical thinking and analysis, note taking, research, essay writing, class discussion, and both independent and collaborative study skills.

Projects such as the medieval castle and cathedral research project encourage an in-depth exploration of key topics. Each year, a field trip to The Cloisters and the Cathedral Church of St. John the Divine enables students to see firsthand the art and architectural styles of the Middle Ages.
