Finding the right content for your students

Learn strategies to browse, select, and assign resources and exercises appropriate for your specific students.  
With thousands of exercises, articles, and instructional videos covering topics from K-12 math to biology, grammar, computer science, history, and more—Khan Academy can be helpful for classrooms at all levels. But how can you find the best resources for your specific students?

Choose a subject for each class

Make sure to select a subject when you create your class. You can check out the subjects our resources cover by clicking on Subjects in the top left corner of our site. When you choose a subject, it helps us guide you toward the resources most commonly assigned for that subject.
Note: Selecting a subject for your class will not prevent you from assigning other content to students or prevent students from practicing on other parts of our site.
You can choose any piece of content on the site—inside your course or out of it—and assign it to specific students or your entire class.
And you can always change the subject you have selected for your course: go to the Settings tab for a class and click Change subject.

Finding material to assign

Option 1: Browse the subject-area content

Often, you will want to assign material connected to what students are learning in your class.
Let’s say I’m an AP physics 1 instructor teaching students about Newton’s laws of motion.
First, I would go to the AP Physics 1 home page and scroll down until I see the unit that covers Newton’s laws of motion. It’s the third unit in the Khan Academy AP physics 1 curriculum.
Next, I would browse the titles of the Learn and Practice resources for Newton’s laws of motion. Perhaps I’m looking for a mixture of videos and articles to assign to students to gain a conceptual understanding of the three laws of motions. Instead of selecting the More on Newton’s second law of motion link, I might narrow my assignments to just the videos with introductory titles like Newton’s second law of motion.
That would lead me to assign the following six resources:
Or perhaps my students have learned about the laws of motion and they are ready to do more practice problems to deepen their understanding. In that case, I might assign just the practice exercises:

Option 2: Search for a topic or resource

Sometimes, you may want to assign a video or exercise from a different subject or grade level than your official class subject. Or, you may just be unsure of where a specific resource or topic is located on Khan Academy.
Let’s say you’re a 7th grade math teacher, for example, but your class is struggling with long division. In this case, you may want to rely on the search bar at the top left of the site to guide you to the appropriate resource. Start by typing in “long division”.
When the results show up – you can sort them by type by just clicking on the resource type here:
Take a look at a resource. If you love it, you can assign it.

Option 3: Brows by Common Core standard (math teachers only)

Perhaps you are looking for a resource aligned to a specific Common Core standard for mathematics. Let’s say you are a 4th grade teacher covering NF.B.3c about adding and subtracting mixed numbers with like denominators.
Start by going to and click Browse our Common Core.
Next, click into the appropriate grade level. Use the left-hand panel to quickly jump to the appropriate standard strand. For this standard, the strand is Number and Operations: Fractions, indicated by the NF at the start of the standard’s title.
Scroll down until you find the exact standard you're looking for. You’ll see a preview of all the Khan Academy exercises aligned to that standard. If you click on the exercises, you can also find related videos and articles to assign for your students.
