In this fun and energetic summer course, students build critical reading and writing skills as they create their very own picture books.

Live instructors guide students (ages 8–11) through lessons in reading, analyzing, and creating a range of original pieces.

This course is recommended for students entering Grade 3 or 4. We recommend that students enroll in Language Arts courses at grade level.

In this course, students build their reading and writing skills by studying the works of picture book masters. Each day in class, students begin by reading and discussing a picture book addressing an advanced Language Arts topic. Then, they try their hand at writing with a unique assignment based on the daily topic. In the final days of the course, students will have the chance to apply what they’ve learned as they write and illustrate a picture book of their very own.

Each lesson includes a balance of lively discussion, independent writing time, and games to get the creative juices flowing!

Students must purchase the required book(s) before the start of the course.

Our instructors hold classes virtually, in a small-sized (10-16 students) videoconferencing classroom. With a small class size, teachers can give individualized attention to each student, providing real-time verbal and written feedback and supporting students' growth as writers.

Our Language Arts summer courses do not include homework. Students receive frequent feedback on their writing and present their work throughout the course.

If you drop a summer course before the start of your first class session, we'll issue a full refund for the course tuition. No refunds will be issued for withdrawing from a summer course after the start of your first class session. We do not accept Language Arts book returns, since they are purchased from a third party.

Our summer course offerings meet five days a week, Monday through Friday. We offer this course in two timing formats. Both cover the same course material.

• The two-week course meets for 3 hours each day.
• The four-week course meets for 1.5 hours each day.

“Peter really appreciates the classes you offer. Especially in these pandemic times your program helps kids to connect and grow and as parents we are very grateful for this. ”

– mother, Irina B.

Art of Problem Solving

Variety of math content supports struggling and advanced learners

Learning rating

Community rating, privacy rating, subjects & topics, take a look inside 8 images.

Pros : Presents information in multiple ways; courses are organized specifically by grade level.

Cons : The forums are a bit hard to navigate; continued use of the program could get a bit pricy over time.

Bottom Line : Separate sections for younger and older students help to teach kids at all levels, from foundational skills up to Math Olympiad training.

• How Can I Teach with This Tool?
• What Is It?
• Is It Good for Learning?

The Art of Problem Solving allows students to focus on math concepts that they're struggling with or (for advanced students) that offer a challenge. The site presents the materials as self-paced for younger students or as online, interactive courses for older students. There's also a large collection of additional resources available on the site, including videos and an extensive forum (over eight million posts and counting) where students discuss all sorts of math concepts. 

The site is best designed for students wishing to work independently on their math knowledge, although some of the materials presented -- such as the videos -- may be good for a teacher to use with a whole class to introduce a topic or give a different perspective on it. If you're a Math Olympiad coach or have students preparing for math contests, you'll find the videos of sample test questions very helpful; many of the resources found here are especially geared toward kids who are preparing to compete at a national level.

The Art of Problem Solving has added a lot of math content over the past few years and now includes videos, interactive courses, and a fun, game-based academy for younger students. The site is divided into different sections, each focusing on a different area of math and different grade levels. The main divisions are AoPS Online, Beast Academy, and AoPS Academy.

AoPS Online provides older students with lessons on everything from pre-algebra foundational skills up to Math Olympiad training. There's also a substantial forum where students can interact with one another to ask -- and answer -- various math problems. The Beast Academy is for younger students and has a fun interface with comic characters, videos, games, and more for grades 2 to 5. Finally, the AoPS Academy is an in-person academy that students can attend. 

Overall, the Art of Problem Solving provides a variety of resources to help struggling students succeed and to encourage and build enrichment for students to challenge themselves. The fact that it's all presented together in one place may also have the bonus effect of encouraging once struggling students to take on greater and greater challenges -- and perhaps be the next Math Olympians. 

The choice of videos, books, forums, online interactive classes, and games (for the younger students) means that students have a number of different ways to learn the material. The Beast Academy, in particular, is very good at providing students with different learning options. The bright colors and fun characters also lend an air of friendless to the site without losing the focus on teaching. 

The forum promotes collaboration among students, but it's hard to navigate, and some of the posts are less about math and more about "kids being kids" in an online environment. But for those who take the time to explore, there's a rich source of information to be found.

Learning Rating

Overall rating.

A variety of content formats gives students of different abilities multiple options for accessing the materials. The forum, though hard to navigate, encourages kids to engage with one another in a safe, friendly way. 

Math content covers a large number of concepts and is structured differently by grade level: webinar lectures for older students and games and comic book characters for young kids.

The Beast Academy supplies kids with lots of hints, and online, interactive classes give students direct access to the teacher. Digging through the forum may provide additional help.

Strong program with emphasis on deep understanding of concepts and love of math. Would highly recommend above most curriculums I have tried.

The K-5 program is strong and could easily be used in any k-6 program. The content is challenging but so strongly done that any level of student could use the program with support.

The art of problem solving program for 6-12 is very challenging. It could be used for all students, but again, would need support. The online classes are excellent, books alone would need strong classroom support. Clearly aimed at high functioning students. This is a math program that goes beyond basic understanding and rote memorization to emphasize true, deep understanding and complex thinking. There are a plethora of problems available and a rich online community.
