This compilation of reading assigned to students everywhere will expand your horizons — and your bookshelves.

In the US, most students are required to read To Kill a Mockingbird during their school years. This classic novel combines a moving coming-of-age story with big issues like racism and criminal injustice. Reading Mockingbird is such an integral part of the American educational experience that we wondered: What classic books are assigned to students elsewhere?

We posed this question to our TED-Ed Innovative Educators and members of the TED-Ed Community. People all over the globe responded, and we curated our list to focus on local authors. Many respondents made it clear in their countries, as in the US, few books are absolutely mandatory. Below, take a look at what students in countries from Ireland to Iran, Ghana to Germany, are asked to read and why.

Afghanistan

Quran
What it’s about: The revelations of God as told to the prophet Muhammad, this is the central religious text of Islam and remains one of the major works of Arabic literature.
Why it’s taught: “Overall, there is no culture of reading novels in my country, which is sad,” says Farokh Attah. “The only book that must be read in school is the holy Quran, and everyone is encouraged to read it starting from childhood.”

Albania

Kronikë në gur (1971) by Ismail Kadare
What it’s about: Known in English as Chronicle in Stone, this novel is told through the eyes of a child and shows how different conquering forces — Italian fascist, Greek and Nazi — ravage a small Albanian city during World War II.
Why it’s taught: Kadare is one of the most critically acclaimed Albanian writers, and was nominated several times for the Nobel Prize in Literature. This book “helps you understand vividly what World War II meant for the people who lived through those events,” says Vaitson Çumaku. “Because it’s from the perspective of a child, it also shows you that there can be optimism during hard times.”

Australia

Tomorrow, When the War Began (1993) by John Marsden
What it’s about: A teenage girl and her friends return from a camping trip to find that an unidentified foreign military force has invaded Australia.
Why it’s taught: This book “speaks to our fear of invasion and our fighting spirit,” says Beth James Waters. It also “beautifully portrays the vastness of and abundant natural dangers in our land.”

Austria

Faust (1787) by Johann Wolfgang von Goethe
What it’s about: In this play, a scholar named Faust makes a pact with Mephistopheles — the devil — because Faust is dissatisfied with life. The devil says he will grant Faust a transcendent moment, but in return, Faust must act as his servant for eternity in hell. Through the devil’s intervention, Faust falls in love with a beautiful young girl named Gretchen. Tragedy ensues.
Why it’s taught: It raises many vast philosophical debates, including science versus spirituality, reason versus passion, and salvation versus damnation, and “it can be interpreted in many ways,” says Barbara Paulmayer. “Faust is not as easy to understand as newer pieces of literature, so it stimulates students to think in a different way.” In addition, its plot and themes have gone on to influence many other works.

Bosnia; Serbia

Na drini ćuprija (1945) by Ivo Andrić
What it’s about: Known in English as The Bridge on the Drina, this novel sweeps through 300 years in a small town near the Mehmed Pasha Sokolović bridge. Its story begins in the 16th-century Ottoman Empire, when the bridge was built, to World War I, when it was partially destroyed.
Why it’s taught: Andrić received a Nobel Prize, and so far he has been the only Nobel Prize winner from Serbia, Croatia and Bosnia. “It is truly a timeless book,” says Martin Kondža. “Its themes and stories also apply to humanity today. The bridge acts as a dumb witness to empires being born and crushed, human lives reaching their peaks and depths, and countries being established and destroyed.”

Brazil

Morte e vida Severina (1955) by João Cabral de Melo Neto
What it’s about: Known in English as The Death of a Severino, this play in verse is about the arduous journey of a man who is fleeing the drought- and poverty-stricken northeastern region of Brazil in search of a better situation and the city.
Why it’s taught: “It shows the dual conditions that the country has always presented and still presents — poor lives, inequality, ignorance, and silent people, versus a city population, with all its advantages — and the distance between these two groups,” says Andrea Rodrigues.

Bulgaria

Under the Yoke (1894) by Ivan Vazov
What it’s about: This novel looks at a Bulgarian village under Ottoman rule and depicts a failed insurrection in the 1870s that helped trigger the country’s eventual breakaway. The large cast of characters includes villagers on both sides of the rebellion.
Why it’s taught: For one thing, Vazov is seen as the father of Bulgarian literature. But, adds Kristine O’Malley, “Being enslaved by the Ottoman Empire and the struggle for independence have shaped the national identity of Bulgarians,” making this book a perennially popular read.

Canada

The Wars (1977) by Timothy Findley
What it’s about: Robert Ross, a 19-year-old Canadian, tries to cope with the death of his sister by enlisting to fight in World War I. Beset by his own demons, he travels to France where he fights in the trenches and sees the worst of warfare — and of humanity.
Why it’s taught: “It’s an iconic Canadian novel. It’s so brutally honest in its depiction of war, sorrow, and coming to terms with an uncaring world in one’s own way,” says Karen Goepen-Wee. “This text does not tread lightly around the angst and horror of World War 1 for Canadian soldiers,” says Will Gourley.

Chile

Sub Terra (1904) by Baldomero Lillo
What it’s about: This short-story collection is about the backbreaking, impoverished, dangerous existence of coal miners in southern Chile in the late 19th century.
Why it’s taught: “Sub Terra represents an important part of Chile’s history,” says Natalia Salamanca Moreno. “These stories show students a lifestyle that is completely different from theirs today, which can help them appreciate what they have now. The stories also emphasize important, timeless family values, like being thankful for your parents and their efforts.”

China

Analects by Confucius
What it’s about: This book is a compilation of the teachings of the ancient philosopher Confucius; it’s believed to have been written sometime between 475 BC and 221 BC.
Why it’s taught: “Teachers want students to learn good morals from the Analects, like showing respect to your parents, learning merit from others no matter their status, and using critical thinking,” says Aylee Lu. “This book remains a cornerstone of Chinese culture.”

Colombia

Cien años de Soledad (1967) by Gabriel García Márquez
What it’s about: This pioneering fictional work of magical realism — known to English-language readers as 100 Years of Solitude — traces the rise and fall of a fictional Colombian town through five generations of the Buendía family, starting in the early 19th century.
Why it’s taught: Márquez is considered one of the most important writers in the Spanish language, and he was awarded the Nobel Prize in Literature in 1982. This novel depicts the violence that has plagued Colombia for decades, and “shows how much corruption and suffering Colombians have endured,” says Daniela Ramirez Barreto. “Yet there is something about us that refuses to give up.”

Cyprus

The Murderess (1903) by Alexandros Papadiamantis
What it’s about: This novella is about an old woman named Hadoula who lives on the island of Skiathos. She murders poor young girls as a kind of mercy killing, since she views their future prospects to be limited and bleak.
Why it’s taught: “It sheds light on the role of women and on gender roles within marriage; these are of great importance in Cyprus and Greece,” says Evanthia Poyiatzi. “And it makes students decide whether the woman’s behavior is ethical or unethical.”

Egypt

The Days (1935) by Taha Hussein
What it’s about: This book is the autobiography of intellectual and writer Hussein, who lived from 1889 to 1973. He became blind at the age of 3 but grew up to be the minister of education in his country and is one of the most influential figures in Egyptian literature.
Why it’s taught: The book teaches students “the importance of gathering knowledge, the need to rebel against traditions and the negative effects of ignorance upon individuals in a society,” says Mahmoud Attalla.

Finland

Seitsemän veljestä (1870) by Aleksis Kivi
What it’s about: Known in English as Seven Brothers, this book is about a quarrelsome family of seven brothers and their struggles in rural Finland. They eventually grow and mature into decent members of society.

Germany

Tagebuch der Anne Frank (1947)
What it’s about: Known in English as The Diary of Anne Frank, this journal was kept by a Jewish girl named Anne Frank as she lived with her family in hiding in Amsterdam under Nazi occupation.
Why it’s taught: “We should never forget what horrors were unleashed by narrow-thinking people,” says Charlotte Böhm.

Ghana; Nigeria

Things Fall Apart (1958) by Chinua Achebe
What it’s about: Set in Nigeria in the 1900s, this novel follows Okonkwo, an Igbo leader and village wrestling champion, his journey to power and glory, and his eventual fall when he fights back against white colonialists.
Why it’s taught: “On the surface, it’s a celebration of African traditionalism and how those ideals were washed away with the coming of the missionaries,” says Ama Y Adi-Dako. “At the heart of it, though, it is a critical look at the concept and drawbacks of African and tribal masculinity.”

India

Autobiography: The Story of My Experiments With Truth (1927-1929) by Mohandas K. Gandhi

Poems by writers such as Hafiz, Sa’Addi, Ferdowsi, Rumi and Khayyam
What they’re about: Love, beauty, joy and other themes.
Why they’re taught: “In Iran, the novel is a relatively newer form of literature,” says Ne Da. “But among our literary classics are abundant poets and poetry. Each poem speaks to a different value.”

Ireland

Ice Man: the Adventures of an Irish Antarctic Hero (2003) by Michael Smith
What it’s about: It’s a biography of Tom Crean, an Irish boy who ran away from home at the age of 15 to join Captain Robert Falcon Scott’s Antarctic voyage. He was also a member of Ernest Shackleton’s Endurance expedition.
Why it’s taught: “It shows that the Irish are ambitious explorers who can triumph over adversity and that through hard work, focus and dedication, everything is possible,” says Naoimh Riordan.

Italy

I Promessi Sposi (1827) by Alessandro Manzoni
What it’s about: Known in English as The Betrothed, this novel takes place in northern Italy in the first half of the 17th century. Italy was not yet a nation, and this book shows the lives of villagers living under repressive Spanish rule as well as the impact of a deadly plague that killed many people.
Why it’s taught: “I Promessi Sposi is one of the two pillars of Italian literature,” says Sofia Ramundo. “It is considered the blueprint for historical novels,” says Michela Sacchi O’Brien.

Everyone wants kids to thrive in school — but what about the teachers who are there to make that happen?

What can parents and community members do that might be actually useful, valued and appreciated by educators? From the deeply practical (yes, money helps) to the more conceptual, here are 18 smart ideas for how you can help a teacher out this year:

1. Offer after-school tutoring

Tutoring is a good way to volunteer. “I would love to see parents creating initiatives to build an after-school tutorial program that is free for students to get extra help on homework,” says Josefino Rivera Jr., who teaches at an international school in Sofia, Bulgaria.

2. Give grocery store gift cards

“If a student is worried about eating, or they are going hungry, then they aren’t going to be focused on learning,” says Craig Zimmer, an educator in Ontario, Canada. That can make kids hard to reach in class — so he suggests donating grocery store gift cards to school counselors to pass them on to families in need. Why school counselors? Because they often know what’s going on at home with students, even if other people don’t.

3. Provide “weekend bags” of healthy food for kids

“The poverty in pockets throughout the United States would shock people (I think),” says Mitzi Stover of California. “Some kids don’t get meals outside of school, so weekends and days off are horrible for them,” says Rita Kitchen, who teaches in Ohio. A grocery bag of fresh, healthy food can help a family get through the weekend and have an immediate positive impact in a student’s life (thus immediately helping a teacher out!).

4. Scrounge art + school supplies

Basic art, school and craft supplies are always in demand. “I’ve had families who can meet the basic needs, but extra paper or a much-needed binder are luxuries,” says Karen Goepen-Wee, who teaches in Alberta, Canada. “Also, students always need craft supplies. Imagine not being able to practice how to write or color or create because your family can’t afford the basics like crayons, glue and craft paper.”

5. Create work-experience opportunities

Ontario-based educator Craig Zimmer wants students to get real-world context for what they’re learning. So, students in science class might visit science labs, while students in art class might work with artists. “Many teenagers have ideas about their future jobs, but never get the opportunity to see which ones really interest them,” agrees Ela Potocka of Warsaw, Poland. “Students need to visit workplaces in administration, government and other fields.”

6. Share your own skills and talents

Parents can help by lending their expertise to schools, or by showing kids what they do all day. “We need more ways to get students invested in their future through career education, mentorships, intern opportunities and field trips — especially in STEM fields,” says Jennifer Parr of Wisconsin. “Especially in high school, students can get lost in the shuffle and could really use more strong adult connections,” says Mitzi Stover in California. And it doesn’t have to be in person — you can talk to student groups halfway around the globe via video calls.

7. Help with teacher recruitment

“Better teachers — in terms of subject matter expertise and soft skills — can make a big difference for a school,” says Vipul Redey, an administrator in Bangalore, India. You might not have the expertise to help hire educators, but you can certainly spread the word about a school’s open teaching positions.

8. Subsidize Internet access

“My immediate school need and challenge is the lack of internet connectivity,” says Fred Sagwe, who teaches information and communications technology in Kisii, Kenya. “A solution like BRCK [a portable WiFi router] can be of great help to the school, parents and the community. If parents and the community can chip in funding for internet data bundles, that would be a godsend.”

9. Donate tech tools

“Schools in our district that are in affluent areas have one-to-one technology paid for by the district, while our school, which is in one of the poorest areas, has an average of four or five devices per class,” says educator Jeri Hammond in Florida, who’d love to figure out how to get a bunch of Kindle Fires for her Kindergarteners and first graders.

10. Donate backpacks, school supplies, or weather-appropriate clothes

“So many children need backpacks and school supplies,” says Camille Stawicki, a literacy coach in Michigan. Particularly in cold weather, there is also a huge need for clean, untorn clothing for needy kids. Appropriate clothing donations may include things like jeans, coats, hats, gloves, socks and boots. “I always ask my classroom to check their homes for gently used clothing and shoes for school-aged children,” says teacher Eric Johnson, who teaches middle school in Mishawaka, Indiana.

11. Teach kids to be resilient …

Parents need to build more resilience in their kids, says Jon Nash of Petone, New Zealand. “Stop protecting kids from the consequences of their own behavior,” he says.

12. … and to have heart and soul

It’s not enough to develop bright minds. We also need to help students to develop good hearts. Parents and community members can help by offering skills training in meditation, compassion and teamwork, says Alex Nemo Hanse of Florida.

13. Support teachers’ professional development

Teachers are always looking for new ways to engage their students and bring new experiences and activities into the classroom. You can support teachers’ leadership, initiative, and development by sharing a TED-Ed program with them! TED-Ed Student Talks program provides free, customizable activities for educators to support their students’ public speaking skills and socio-emotional well-being as they share their ideas with each other and the world.

14. Organize a weekend for the community to paint and decorate a school

“Our building is old and wants to be new,” says Mohammad Azam of Khairpur, Pakistan. Maybe local businesses could donate furniture. Be creative in kitting out a school. “We just finished a complete renovation of our auditorium,” says Michael Ashe of California. “Only a third was paid for by district funds. The rest came from donated services, equipment, and grants. We even added TV production!”

15. Endorse vocational skills

“Students need to be allowed to take a vocational path and be praised for doing so,” says Kate Ferrer of Wales.

16. Show up

Let’s find ways to involve parents in their children’s learning, while also teaching parenting skills, suggests Sarah Peterson Sheridan of Illinois. “It would be wonderful to fill our schools in the evening with parent/child cooking classes, Zumba, art classes and field trips.”

17. Be an engaged parent

“We need parents to get involved, ask the difficult questions, and listen to the answers, without aggression or blind belief that ‘their’ child is perfect,” says educator Iain Bogie from the UK. Meanwhile, sitting on a school board can be infinitely helpful. “We need parents or community members running for school board positions and roles of formal leadership,” says Kathleen Harsy of Illinois. “Contested positions would be a great problem to have!”

18. Respect your teachers!

“We all want to be regarded as experts and respected for our expertise by parents and community,” says Jenny Lehotsky of Illinois. Adds Jennifer Ward from Michigan, “Teachers need to feel valued by their administration as well. Meaningful and purposeful use of staff development time that incorporates the collective knowledge and experience of teachers is imperative for building a collaborative and creative school culture.”

Mathematician Eduardo Sáenz de Cabezón suspects that when people ask him what’s the use of math, they’re really asking why they had to study math in school. As a mathematics professor at the University of La Rioja in northeastern Spain, Sáenz de Cabezón (TED Talk: Math is forever) has come up with a spirited defense of his chosen profession. Math, he believes, is nothing less than a quest for eternal truth. Here’s why:

Math reveals unfathomable truths. Take a regular sheet of paper and start folding. If the piece of paper were big enough to be folded 50 times, Sáenz de Cabezón says, “its thickness would extend almost the distance from the Earth to the Sun.” If you’re now trying to imagine how a sheet of paper, folded 50 times, can rise nearly 93 million miles into space, you’re experiencing the strange thrill of a mathematical proof. “Your intuition tells you it’s impossible,” he says. “Do the math and you’ll see it’s right. That’s what math is for.”

Math can be as beautiful as poetry — or love. “Science operates on intuition, creativity. Math controls intuition and tames creativity,” says Sáenz de Cabezón. He admits that his colleagues fall into two camps when they’re asked why math matters: attackers and defenders. “The attacking ones are mathematicians who would tell you this question makes no sense, because mathematics have a meaning all their own,” Sáenz de Cabezón says. “There’s no point in constantly searching for all possible applications. What’s the use of poetry? What’s the use of love? What’s the use of life itself?” They have a point, he says — and so do the defenders. “Those who stand in defense tell you, ‘Even if you don’t realize it, friend, math is behind everything.’ Those guys, they always bring up bridges and computers. ‘If you don’t know math, your bridge will collapse.’” Also true. But Sáenz de Cabezón suspects that neither answer conveys the private thrill that mathematicians experience with every breakthrough in their field — and every push to help us better understand the world.

Math endures. Anyone can posit a theory of how the universe works, but math leaves no room for conjecture. Consider how long mathematicians puzzled over a proposal by Pappus of Alexandria, who theorized in around 300 A.D. that a hexagon was surely the most efficient shape for covering an infinite flat field. “But he didn’t prove it,” says Sáenz de Cabezón. “It remained a conjecture: ‘Hexagons!’” The debate raged for 1,700 years, until in 1999 American mathematician Thomas Hales offered decisive proof of what Pappus had discovered and what bees instinctively know — the most efficient shape is indeed a hexagon. “We mathematicians devote ourselves to coming up with theorems,” says Sáenz de Cabezón. These, in essence, are “eternal truths,” discoveries that are possibly the most enduring things we will ever encounter in our lifetimes.” You probably said or were told at some point that diamonds are forever,” Sáenz de Cabezón says. “That depends on your definition of forever. A theorem? That really is forever.”
